Ammonium Carbonate (Product Code: SCI-555/241) is an analytical reagent grade ammonium salt used as a group reagent in qualitative salt analysis and to demonstrate thermal decomposition in school and college chemistry laboratories. It is the reagent that separates the alkaline earth cations, and it is packed as 100 g with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to institutions assembling a salt analysis kit for school and college practicals.

Specifications

What Is Ammonium Carbonate Used For?

In the classic cation scheme, ammonium carbonate is added after ammonium chloride and ammonium hydroxide; barium, strontium and calcium then come down as white carbonate precipitates, while magnesium stays in solution because of the ammonium buffer. The precipitate is dissolved in acetic acid, and the individual ions are confirmed with further reagents and flame colours. This step is the heart of the Group V separation that students practise in senior practical examinations.

Warm a little of the solid in a dry test tube and it disappears almost completely, breaking down into ammonia, carbon dioxide and water vapour. Moist red litmus turns blue and limewater turns milky, identifying two of the gases in one experiment. Because it loses ammonia slowly even at room temperature, keep the bottle tightly stoppered in a cool place and prepare reagent solution freshly when accuracy matters.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, supplies Ammonium Carbonate from Ambala, Haryana, to schools, colleges and dealers who stock inorganic analysis reagents. The other group reagents and test papers can be added to the same enquiry. See the ScienceLab profile page for company information.

Related Laboratory Equipment

• Ammonium Chloride 200 g — added first to buffer the solution and keep magnesium dissolved.
• Ammonium Hydroxide (Ammonia) — makes the solution alkaline before the carbonate goes in.
• Barium Chloride 200 g — a known barium salt on which to practise the carbonate precipitation.
• Calcium Hydroxide 200 gm — for limewater to detect carbon dioxide released on heating.
• Litmus Paper (Type Red) — turns blue in the ammonia given off.

Other analysis reagents are grouped in the Laboratory Equipment category.

Frequently Asked Questions

What is Ammonium Carbonate used for in salt analysis?
Ammonium Carbonate is the group reagent that precipitates barium, strontium and calcium as carbonates in the presence of ammonium chloride and ammonium hydroxide. This separates the alkaline earth cations from magnesium and the alkali metals during systematic qualitative analysis.

What happens when Ammonium Carbonate is heated?
Ammonium Carbonate decomposes on gentle heating into ammonia, carbon dioxide and water vapour, leaving little or no residue. The ammonia turns moist red litmus blue and the carbon dioxide turns limewater milky, making it a useful thermal decomposition demonstration.

Why does Ammonium Carbonate smell of ammonia?
Ammonium Carbonate slowly decomposes even at room temperature, releasing ammonia gas, which gives the characteristic sharp smell. Keeping the container tightly closed and cool slows this loss and helps the reagent stay effective for analysis.

What grade and pack size does this listing offer?
This Ammonium Carbonate, product code SCI-555/241, is listed as analytical reagent grade in a 100 g pack. It is supplied with an MSDS covering its hazards, handling, storage and disposal for your laboratory records.

What is the shelf life of Ammonium Carbonate?
Shelf life depends on the chemical, its grade and storage conditions, and Ammonium Carbonate in particular loses ammonia if left open. Ask us for the expiry date of the batch you are quoted.

Sodium Carbonate 200 g (Product Code: SCI-558/242) is an analytical reagent grade sodium salt, commonly known as soda ash or washing soda, used to standardise acids in titrations and to demonstrate carbonate reactions in school and college chemistry labs. It suits volumetric analysis courses and comes as a 200 g pack with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools putting together a titration kit or a carbonate practical.

Specifications

What Is Sodium Carbonate Used For?

Weighed accurately and dissolved in distilled water, sodium carbonate gives a standard solution against which hydrochloric acid is titrated using methyl orange indicator. Once the acid concentration is known, students can move on to other acid–base titrations with confidence. For standardisation work, dry the solid first as your practical manual directs, since hydrated or damp material changes the mass taken.

Outside titration, sodium carbonate solution fizzes with acids to give carbon dioxide that turns limewater milky, precipitates insoluble carbonates from solutions of calcium and other metal ions, and shows how hard water can be softened. It is also used to make the sodium carbonate extract for anion tests in salt analysis. The solution is alkaline and irritating to the eyes, so goggles should be worn.

What to Specify When Ordering

• The number of 200 g packs needed for each laboratory or campus.
• Whether your method calls for the anhydrous form, so we can confirm which form the quoted batch is.
• Companion items for the titration, such as hydrochloric acid, methyl orange and conical flasks.
• Delivery location and any vendor or tender forms your institution uses.

Supplier

Jain Scientific Equipments Private Limited supplies Sodium Carbonate 200 g under its ScienceLab trading name from Ambala, Haryana, to schools, colleges, dealers and importers. We can quote the acid, indicator and titration glassware in the same enquiry. For company background, visit the ScienceLab profile page.

Related Laboratory Equipment

A sodium carbonate titration or carbonate-reactions practical typically adds:

• Hydrochloric Acid 2000 ml — the acid standardised against sodium carbonate.
• Metiloranzh (Indicator) — methyl orange, the usual indicator for carbonate–acid titrations.
• Conical Jar (Erlenmeyer) 250 ml — a titration flask that allows swirling without splashing.
• Sodium Hydrogen Carbonate — the hydrogen carbonate for comparing reactions with acid.
• Calcium Chloride 200g — a calcium salt that gives a white carbonate precipitate with sodium carbonate.

Explore the Laboratory Equipment category for more titration reagents.

Frequently Asked Questions

Why is Sodium Carbonate used to standardise hydrochloric acid?
Sodium Carbonate can be weighed accurately in dry form and reacts completely with hydrochloric acid, so a solution of known concentration serves as a primary standard. Titrating the acid against it with methyl orange gives the acid's exact concentration for later experiments.

Is Sodium Carbonate 200 g anhydrous or hydrated?
The listing for Sodium Carbonate 200 g states analytical reagent grade but does not specify the anhydrous or decahydrate form. If your practical needs a particular form, mention it in your enquiry and we will confirm which form the quoted batch is.

What else can Sodium Carbonate demonstrate?
Sodium Carbonate reacts with acids to release carbon dioxide, precipitates calcium and other metal ions as insoluble carbonates, and softens hard water. It is also used to prepare the sodium carbonate extract for anion testing in qualitative salt analysis.

Is Sodium Carbonate hazardous?
Sodium Carbonate is an irritant, especially to the eyes, and its solution is alkaline. Wear goggles, avoid raising dust, and follow the MSDS supplied with each 200 g pack for first aid, storage and disposal guidance.

What is the shelf life of Sodium Carbonate 200 g?
Shelf life depends on the chemical, its grade and storage conditions, so we do not state a fixed period for Sodium Carbonate 200 g. Ask us for the expiry date of the batch you are quoted and keep the pack sealed and dry.

Can we order Sodium Carbonate for several laboratories?
Yes. Sodium Carbonate 200 g can be ordered in the number of packs your laboratories need, for delivery within India and to international markets. Send quantities and destinations through our contact page for a quotation.

Calcium Carbonate (Granules) 200 g (Product Code: SCI-561/243) is analytical reagent grade calcium carbonate in granular form, used to generate carbon dioxide with dilute acid and to study reaction rates in school and college chemistry labs. The granules react at a steady, controllable pace that suits gas preparation, and the pack holds 200 g with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which also lists gas collection apparatus such as side-tube flasks.

Specifications

What Are Calcium Carbonate Granules Used For?

Granules placed in a flask or Kipp generator and covered with dilute hydrochloric acid give a steady stream of carbon dioxide that can be collected over water or by upward displacement of air. Students then test the gas with limewater, show that it puts out a burning splint, and fill gas jars to demonstrate that it is denser than air. Because granules keep their shape, the reaction does not froth up and block the delivery tube as fine powder can.

Granules also give the slower curve in rate-of-reaction investigations: comparing the same mass of granules and powder with the same acid shows clearly how surface area controls reaction speed. Avoid sulphuric acid for gas generation, because insoluble calcium sulphate coats the granules and stops the reaction; hydrochloric acid is the usual choice.

What to Specify When Ordering

• Form: granules (this listing) for steady gas generation, or the powder listing if you mainly compare rates.
• How many 200 g packs each laboratory needs for the term.
• Whether the acid and gas-generation glassware should be quoted with it.
• Delivery address and any vendor-registration forms.

• Calcium Hydroxide 200 gm — for the limewater test that identifies carbon dioxide.
• Calcium Carbonate (Powder) 200 g — the powdered form for surface-area comparisons.

The Laboratory Equipment category has further gas-preparation items.

Frequently Asked Questions

What is Calcium Carbonate (Granules) 200 g used for?
Calcium Carbonate (Granules) 200 g is used mainly to generate carbon dioxide by reaction with dilute hydrochloric acid in a flask or gas generator. It also serves in rate-of-reaction work, where granules are compared with powder to show the effect of surface area.

Why use granules rather than powder for making carbon dioxide?
Granular Calcium Carbonate reacts steadily and does not froth or clog the apparatus, so the gas flow is easier to control and collect. Powder reacts much faster, which helps rate comparisons but is less convenient for filling gas jars.

Can sulphuric acid be used with calcium carbonate granules?
Sulphuric acid is not recommended with Calcium Carbonate (Granules) 200 g, because the calcium sulphate formed is only slightly soluble and coats the granules, so the reaction quickly slows and stops. Dilute hydrochloric acid is the standard choice.

What does the pack contain?
This listing, code SCI-561/243, contains 200 g of analytical reagent grade Calcium Carbonate in granule form, supplied with an MSDS for your safety records. The granule size is not specified in the listing; ask us if your apparatus needs a particular size.

What is the shelf life of Calcium Carbonate (Granules) 200 g?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Calcium Carbonate (Granules) 200 g. Ask us for the expiry date of the batch you are quoted, and store it closed and dry.

Calcium Carbonate (Powder) 200 g (Product Code: SCI-563/244) is powdered calcium carbonate of analytical reagent grade, used for rate-of-reaction, neutralisation and thermal decomposition experiments in school and college chemistry laboratories. As a powder it offers a large surface area and reacts far faster with acid than granules, and it is supplied as a 200 g pack with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, within its range of educational laboratory equipment in India.

Specifications

What Is Calcium Carbonate Powder Used For?

In the standard rate experiment, a flask of dilute hydrochloric acid with a cotton-wool plug sits on a balance; the powder is tipped in and the mass is recorded as carbon dioxide escapes. Repeating with granules of the same mass gives a much slower curve, so students can see and graph how surface area changes reaction rate. The same set-up can then be used to vary acid concentration or temperature.

Powdered calcium carbonate also neutralises acid in the classic indigestion-remedy investigation, where students find how much powder is needed to bring an acid solution to neutral with indicator paper. Heated strongly in a crucible, it decomposes to calcium oxide (quicklime) and carbon dioxide, introducing thermal decomposition and the lime cycle. Store it dry and pour it gently to limit dust.

What to Specify When Ordering

• Physical form: powder (this listing) for fast reactions, or granules for controlled gas generation.
• Number of 200 g packs for your class groups.
• Any balance, flasks or indicator paper you want quoted for rate and neutralisation work.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies Calcium Carbonate (Powder) 200 g from Ambala, Haryana, to institutions and laboratory dealers. The powder and granule forms can be quoted together for comparison practicals. Company information is on the ScienceLab profile page.

Related Laboratory Equipment

Rate, neutralisation and decomposition practicals with Calcium Carbonate (Powder) 200 g often pair it with:

• Calcium Carbonate (Granules) 200 g — the granular form for comparing surface area and reaction speed.

• Conical Jar (Erlenmeyer) 250 ml — holds the acid during the mass-loss experiment.
• Universal PH Indicator (Indicator) — shows when the powder has neutralised the acid.
• Calcium Oxide (Granules) 200 g — the oxide formed on strong heating, for comparison.

Visit the Laboratory Equipment category for the wider reagent range.

Frequently Asked Questions

Why is Calcium Carbonate (Powder) 200 g used in rate-of-reaction experiments?
Calcium Carbonate (Powder) 200 g has a much larger surface area than granules, so it reacts faster with acid. Comparing the powder with granules of equal mass lets students measure and graph how surface area affects reaction rate.

How do students measure the reaction rate?
Students add Calcium Carbonate (Powder) to dilute acid in a flask standing on a balance and record the mass at regular intervals. The falling mass shows carbon dioxide escaping, and plotting it against time gives the rate curve.

Can the powder be used to prepare carbon dioxide?
It can, but Calcium Carbonate (Powder) reacts so quickly that it may froth and is hard to control in a gas generator. For steady gas preparation the granular listing is usually more convenient, while the powder suits rate and neutralisation studies.

What happens when calcium carbonate powder is heated strongly?
When Calcium Carbonate (Powder) is heated strongly in a crucible it decomposes into calcium oxide and carbon dioxide. Adding a few drops of water to the cooled solid, then indicator, reveals the alkaline calcium hydroxide formed, completing a lime-cycle demonstration.

What is the shelf life of Calcium Carbonate (Powder) 200 g?
Shelf life depends on the chemical, its grade and storage conditions, so we give no set period for Calcium Carbonate (Powder) 200 g. Ask us for the expiry date of the batch you are quoted and keep it in a dry cupboard.

What is included with each pack?
Each Calcium Carbonate (Powder) 200 g pack, code SCI-563/244, holds analytical reagent grade powder and comes with an MSDS describing handling, storage and disposal. Schools and dealers can order multiple packs for India and international markets.

Calcium Carbide (Product Code: SCI-565/245) is an analytical reagent grade inorganic compound used to prepare acetylene (ethyne) gas by reaction with water in school and college organic chemistry laboratories. It gives students a simple route to an unsaturated hydrocarbon for bromine-water and permanganate tests, and it comes as a 200 g pack with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its chemistry lab equipment and reagent range.

Specifications

What Is Calcium Carbide Used For?

Water dripped slowly from a dropping funnel onto a few pieces of calcium carbide in a side-tube flask produces acetylene, which is collected over water in test tubes or gas jars. Bubbled through bromine water, the gas removes the orange colour; with dilute alkaline potassium permanganate it turns the purple solution brown, both confirming a carbon–carbon multiple bond. A small tube of acetylene burns with a very sooty, luminous flame, a vivid contrast with methane.

The residue left in the flask is calcium hydroxide, so a drop of indicator shows it is alkaline. Acetylene generated from carbide often carries a garlic-like smell from trace impurities, so work in a well-ventilated room, keep flames away while generating the gas, and ignite only small test-tube samples. Store the pack tightly sealed in a dry place, because moisture in the air slowly releases flammable gas.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies Calcium Carbide from Ambala, Haryana, for hydrocarbon practicals in schools and colleges. Bromine water, permanganate and gas-generation glassware can be quoted in the same enquiry. Learn more on the ScienceLab profile page.

Related Laboratory Equipment

Preparing and testing acetylene from Calcium Carbide usually involves:

• Conical Flask with Side Tube (Erlenmajer Bunsen) — the generating flask, with an outlet for the gas.
• Rubber Tube (Laboratory) — carries the acetylene to the collecting tubes.
• Bromine (Water Bromine) — decolourises in the test for unsaturation.
• Potassium Permanganate 500 g — for the permanganate test in which purple turns brown.
• Safety Goggles — eye protection while generating and igniting the gas.

Further organic reagents are listed in the Laboratory Equipment category.

Frequently Asked Questions

What is Calcium Carbide used for in the chemistry lab?
Calcium Carbide is used to generate acetylene (ethyne) by controlled reaction with water. Students then test the gas for unsaturation with bromine water and potassium permanganate and observe its sooty flame, a practical introduction to alkynes.

How is acetylene prepared from Calcium Carbide?
Place a few pieces of Calcium Carbide in a side-tube flask and add water slowly from a dropping funnel. The acetylene formed is collected over water, while the calcium hydroxide residue stays in the flask; control the water flow to keep the reaction steady.

How should Calcium Carbide be stored?
Keep Calcium Carbide in its tightly sealed container in a dry, well-ventilated store away from water, acids and ignition sources. Moist air slowly releases flammable acetylene, so reseal the pack immediately after use and follow the MSDS.

What grade and pack size is supplied?
This Calcium Carbide, code SCI-565/245, is listed as analytical reagent grade in a 200 g pack with an MSDS. A few small pieces are enough for each gas preparation, so one pack supports repeated class demonstrations.

What is the shelf life of Calcium Carbide?
Shelf life depends on the chemical, its grade and storage conditions, and Calcium Carbide slowly degrades if moisture enters the pack. Ask us for the expiry date of the batch you are quoted when you send your enquiry.

Can Calcium Carbide be supplied to institutions abroad?
Calcium Carbide releases a flammable gas on contact with water, so international consignments need suitable packing and a carrier that accepts it. Share the destination and quantity on the contact page, and ScienceLab will advise on supply to India and international markets.

Tin-Grain (Granules) (Product Code: SCI-567/246) is granulated tin metal of analytical reagent grade, used for reactivity-series experiments and as the reducing metal with hydrochloric acid in college organic chemistry. The granular form gives a good surface for reaction while staying easy to weigh and handle, and it comes as a 100 g pack with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to colleges and schools stocking a chemistry reagent cabinet.

Specifications

What Are Tin Granules Used For?

Tin sits just above hydrogen in the reactivity series, so granules react only slowly with dilute hydrochloric acid, releasing a few bubbles of hydrogen, and more readily when the acid is warm or concentrated. A granule left in copper sulphate solution gradually gains a coating of copper, while tin in zinc sulphate solution shows no change. This pair of displacement tests fixes tin's position between zinc and copper.

In college organic practicals, tin and concentrated hydrochloric acid reduce nitrobenzene to aniline, the classic preparation of an aromatic amine; the tin is oxidised to tin chloride in the process. Tin granules themselves are relatively low-risk, but the acids and organic reagents used with them are not, so carry out the reduction in a fume cupboard. Keep the granules in a closed, labelled jar between sessions.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab and supplies Tin-Grain (Granules) from Ambala, Haryana, to colleges, schools and dealers. Nitrobenzene, hydrochloric acid and the other metals for reactivity comparisons can be quoted together. See the ScienceLab profile page for more about the company.

Related Laboratory Equipment

Reduction and reactivity experiments with Tin-Grain (Granules) typically also use:

• Nitrobenzene — reduced to aniline by tin and hydrochloric acid.
• Hydrochloric Acid 2000 ml — the acid for hydrogen evolution and for the tin reduction.
• Granulated Zinc (Granules) 200 g — a more reactive metal for side-by-side comparison.
• Hydrated Copper Sulfate 500 g — for the displacement test in which tin gains a copper coating.
• Tin Chloride (II) — the tin salt formed in the reaction, stocked separately for tin ion tests.

More metals and reagents appear in the Laboratory Equipment category.

Frequently Asked Questions

What is Tin-Grain (Granules) used for?
Tin-Grain (Granules) is used in reactivity-series and displacement experiments and, with concentrated hydrochloric acid, as a reducing agent in organic chemistry, most famously to convert nitrobenzene into aniline. The granules are also a convenient source of tin for preparing tin salts.

Is Tin-Grain the same as granulated tin?
Yes. Tin-Grain (Granules) is tin metal in granulated form, also sold as tin granules or granulated tin. This listing, code SCI-567/246, is analytical reagent grade in a 100 g pack; the granule size is not specified, so ask us if it matters.

How does tin react with hydrochloric acid?
Tin-Grain (Granules) reacts slowly with dilute hydrochloric acid and faster with warm concentrated acid, releasing hydrogen and forming tin(II) chloride. The slow rate compared with zinc or magnesium helps students place tin just above hydrogen in the reactivity series.

How should tin granules be stored?
Store Tin-Grain (Granules) in a closed, labelled container in a dry reagent cabinet, apart from acids and oxidisers. Tin resists corrosion well, but keeping it clean and dry preserves a bright surface for displacement experiments.

What is the shelf life of Tin-Grain (Granules)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Tin-Grain (Granules). Please ask us for the expiry date of the batch you are quoted along with your quotation.

How can colleges order Tin-Grain (Granules) with organic reagents?

Potassium Chloride 500 g (Product Code: SCI-569/247) is an analytical reagent grade potassium salt used to make salt bridges, conductivity solutions and solubility-curve samples in school and college chemistry laboratories. The 500 g pack suits departments that use the salt across many benches or practical sessions, and it arrives with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools and colleges setting up an electrochemical cell kit.

Specifications

What Is Potassium Chloride Used For?

In a galvanic cell practical, a U-tube or strip of filter paper soaked in saturated potassium chloride solution forms the salt bridge that completes the circuit between the zinc and copper half-cells without mixing them. Potassium and chloride ions move at similar speeds, which keeps the bridge from distorting the measured voltage. Potassium chloride solutions of known concentration are also a common reference for checking conductivity meters and for electrolyte-conductivity demonstrations.

Because its solubility rises steadily with temperature, potassium chloride is a good salt for plotting a solubility curve from crystallisation temperatures. It gives a lilac flame colour, seen most clearly through blue cobalt glass, and a white silver chloride precipitate with acidified silver nitrate, so it also serves as a known sample in flame and chloride tests. Keep the pack sealed, as the salt picks up moisture and cakes in humid weather.

What to Specify When Ordering

• Pack size: this listing is the 500 g pack; smaller packs of the same salt appear under related items.
• Number of packs per department or campus.
• Companion apparatus, such as the galvanic cell or conductivity set.
• Delivery location, plus the vendor-registration details your institution requires.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies Potassium Chloride 500 g from Ambala, Haryana, to schools, colleges, dealers and importers.

Potassium Chloride 500 g is used to prepare salt bridges for galvanic cells, electrolyte solutions for conductivity work, solubility-curve samples and known samples for flame and chloride tests. The larger pack suits departments running these practicals across many groups.

Why is potassium chloride used in salt bridges?
Potassium and chloride ions move through solution at almost the same speed, so a Potassium Chloride salt bridge carries current between half-cells without adding a significant extra voltage. The salt is also very soluble, readily available and unreactive with common electrodes.

How does this listing differ from other potassium chloride packs?
This listing, code SCI-569/247, is the 500 g pack of analytical reagent grade Potassium Chloride with MSDS. Smaller packs of the same salt appear in our related items; choose by how much your laboratory uses in a term.

How should Potassium Chloride be stored?

Ammonium Chloride 200 g (Product Code: SCI-571/248) is an analytical reagent grade ammonium salt, also called sal ammoniac, used to demonstrate sublimation, prepare ammonia gas and buffer solutions in qualitative analysis in school and college chemistry labs. It is packed as 200 g and comes with an MSDS for the laboratory safety file. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier for schools, colleges and dealers.

Specifications

What Is Ammonium Chloride Used For?

Heated gently at the bottom of a dry test tube, ammonium chloride seems to vanish and reappear as a white solid on the cooler upper wall. In fact it dissociates into ammonia and hydrogen chloride, which recombine as they cool, so the demonstration illustrates both sublimation and a reversible reaction. The same behaviour lets students separate it from a mixture with common salt or sand.

Warmed with calcium hydroxide, ammonium chloride releases ammonia, detected by its smell and by moist red litmus turning blue; this is the standard school preparation of the gas and the basis of the test for ammonium ions. In cation analysis it is added with ammonium hydroxide to hold back the hydroxide concentration, so that group III hydroxides precipitate while later-group ions stay dissolved. It also dissolves with a clear drop in temperature, a simple endothermic example.

Supplier

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, supplies Ammonium Chloride 200 g from Ambala, Haryana, to schools, colleges and dealers in India and international markets. Calcium hydroxide, ammonia solution and test tubes for the same practicals can be added to one enquiry. Visit the ScienceLab profile page for company background.

Related Laboratory Equipment

Sublimation, ammonia preparation and group analysis with Ammonium Chloride 200 g usually call for:

• Calcium Hydroxide 200 gm — heated with ammonium chloride to generate ammonia gas.
• Ammonium Hydroxide (Ammonia) — combined with ammonium chloride as the buffer in group analysis.
• Test Tube 25 x 200mm — a large borosilicate tube for the sublimation demonstration.
• Test Tube Clips — hold the tube safely while it is heated.
• Ammonium Carbonate — the group reagent used after the ammonium chloride buffer stage.

Additional reagents are available in the Laboratory Equipment category.

Frequently Asked Questions

Does Ammonium Chloride really sublime?
Ammonium Chloride appears to sublime, but on heating it actually dissociates into ammonia and hydrogen chloride gases, which recombine into a white solid on the cooler part of the tube. Teachers use it to show both apparent sublimation and a reversible reaction.

How is ammonia prepared from Ammonium Chloride 200 g?
Mix Ammonium Chloride with calcium hydroxide and warm the mixture in a test tube; ammonia gas is released and can be collected by upward delivery because it is lighter than air. Moist red litmus turning blue confirms the gas.

Why is ammonium chloride added in cation analysis?
Ammonium Chloride supplies ammonium ions that suppress the hydroxide concentration of ammonia solution. This lets iron, aluminium and chromium hydroxides precipitate in group III while zinc, manganese, magnesium and other later-group ions remain dissolved for separate testing.

What grade and pack size is this?
This Ammonium Chloride, product code SCI-571/248, is listed as analytical reagent grade in a 200 g pack. The MSDS supplied with it explains the irritant hazards, storage conditions and safe disposal of the salt.

What is the shelf life of Ammonium Chloride 200 g?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is given for Ammonium Chloride 200 g. Ask us for the expiry date of the batch you are quoted, and keep the container dry and closed.

Is Ammonium Chloride hazardous to handle?
Ammonium Chloride is harmful if swallowed and irritating to the eyes, and heating it gives off irritating fumes. Heat only small amounts in a ventilated room, wear goggles, and follow the MSDS supplied with each 200 g pack.
