Nickel Chloride (Product Code: SCI-592/257) is an analytical reagent grade nickel(II) chloride used to show the colour chemistry, complex formation and electroplating of nickel in college and senior school laboratories. Its solutions are green, and it is supplied in a 100 g pack together with an MSDS, a convenient quantity for demonstrations and small-group practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Nickel Chloride Used For?

Nickel(II) ions give pale green solutions. Adding ammonia first precipitates green nickel hydroxide, which then dissolves in excess ammonia to give a deep blue-violet ammine complex, a clear classroom demonstration of ligand exchange. In salt analysis, nickel is confirmed with dimethylglyoxime in ammoniacal solution, which gives a bright rose-red precipitate.

Vocational and electrochemistry classes use nickel salt solutions in electroplating demonstrations, depositing a thin nickel layer on a cleaned copper or brass object connected as the cathode. Nickel compounds can cause skin allergy and are harmful if dust is inhaled or swallowed, so use gloves, goggles and a well-ventilated bench, and collect used solutions as heavy-metal waste.

Tin Chloride (II) (Product Code: SCI-595/258) is an analytical reagent grade tin(II) chloride, also known as stannous chloride, used as a reducing agent in qualitative analysis and redox demonstrations in college and school chemistry laboratories. It comes as a 100 g pack with an MSDS and is usually made up into a fresh acidified solution before each practical session. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its lab chemicals for teaching laboratories.

Specifications

What Is Stannous Chloride Used For?

Stannous chloride is a reducing agent: it decolourises iodine solution, turns yellow-brown iron(III) solutions pale green as they are reduced to iron(II), and is used in redox lessons to show electron transfer between ions. In qualitative analysis it identifies mercury(II), first giving a white precipitate of mercury(I) chloride that turns grey as metallic mercury forms.

In plain water, tin(II) chloride hydrolyses and turns cloudy as an insoluble basic salt forms, so solutions are prepared in dilute hydrochloric acid, and many teachers add a granule of tin metal to the bottle to slow oxidation by air. The solid and its solutions can burn or irritate skin and eyes, so wear gloves and goggles and keep the pack tightly closed.

What to Specify When Ordering

• Product code SCI-595/258 and the number of 100 g packs.
• Whether tin granules and hydrochloric acid for preparing the solution should be quoted too.
• Delivery destination, in India or overseas.

Supplier

Chemistry departments assembling qualitative analysis reagent sets can obtain Tin Chloride (II) from ScienceLab, the trading name under which Jain Scientific Equipments Private Limited of Ambala supplies laboratory chemicals and apparatus. One enquiry can cover this reducing agent together with the acids, metals and glassware used in the same tests. The ScienceLab profile describes the company.

Related Laboratory Equipment

Reagents and storage that go with stannous chloride in solution preparation and redox tests:

• Tin-Grain (Granules) — added to the stock bottle to keep the solution reduced.
• Hydrochloric Acid — prevents hydrolysis when preparing the solution.
• Iron Chloride (III) — reduced to iron(II) in a simple redox demonstration.
• Potassium Iodine-Iodine Solution — decolourised by stannous chloride.
• Reagent Bottle Narrow Mouth, Amber Glass — for storing the prepared solution.

View the complete Laboratory Equipment listing.

Frequently Asked Questions

Is Tin Chloride (II) the same as stannous chloride?
Yes. Tin Chloride (II) and stannous chloride are two names for tin(II) chloride, SnCl₂. ScienceLab lists it as Tin Chloride (II), code SCI-595/258, in a 100 g analytical reagent pack with an MSDS.

Why does Tin Chloride (II) solution turn cloudy?
Tin Chloride (II) hydrolyses in plain water and forms an insoluble basic tin salt, which makes the solution cloudy. Dissolving it in dilute hydrochloric acid prevents this, and a small piece of tin metal in the bottle slows oxidation by air.

What is Tin Chloride (II) used for in qualitative analysis?
Tin Chloride (II) is used mainly as a reducing agent. It confirms mercury(II) ions by giving a white precipitate that turns grey, and it reduces iron(III) to iron(II), which is useful in redox demonstrations and analytical procedures.

How should Tin Chloride (II) be stored?
Store Tin Chloride (II) tightly closed in a cool, dry cupboard away from oxidising agents, because air and moisture slowly convert it to tin(IV) compounds. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Is Tin Chloride (II) hazardous?
Tin Chloride (II) can burn or irritate skin and eyes, and its dust irritates the airways. Wear gloves and goggles, avoid breathing dust, and follow the MSDS supplied with the 100 g pack for first-aid and disposal guidance.

Can Tin Chloride (II) be ordered with other qualitative analysis reagents?
Yes. Tin Chloride (II) can be quoted together with hydrochloric acid, tin granules, glassware and other salt analysis reagents from Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala. List everything on the contact page or in the enquiry cart.

Lithium Chloride (Product Code: SCI-599/260) is an analytical reagent grade lithium chloride (LiCl) used to produce the crimson lithium flame and to study alkali metal chemistry in school and college laboratories. Teachers use it as the lithium sample in flame-test sets, and it is packed as 100 g with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which provides chemistry consumables to buyers in India and international markets.

Specifications

What Is Lithium Chloride Used For?

A little lithium chloride on a clean nichrome or platinum wire, moistened with dilute hydrochloric acid and held in a non-luminous flame, gives an intense crimson-red colour. Setting it beside strontium, also red, and calcium, brick-red, helps students learn to tell similar colours apart, and viewing the flames through a hand spectroscope shows each metal's own line spectrum.

Lithium chloride is one of the most water-soluble and hygroscopic common salts, a good example when discussing how lithium differs from sodium and potassium, and the reason lithium salts are used to control humidity. Keep the lid firmly closed so the powder does not absorb moisture and clump, and avoid swallowing or inhaling the dust, as lithium salts are harmful if ingested.

Supplier

Schools building a flame-test collection can order Lithium Chloride from ScienceLab, the name under which Jain Scientific Equipments Private Limited, Ambala, supplies reagents and laboratory apparatus. The other chlorides and burners used in flame tests are listed in the same catalogue, so a complete set can go on one enquiry. Company details are on the ScienceLab profile.

Related Laboratory Equipment

Salts and apparatus for a flame-test comparison with lithium chloride:

• Strontium Chloride — another red flame, for side-by-side comparison.
• Barium Chloride — gives a pale green flame.
• Potassium Chloride 100 g — shows the lilac potassium flame.
• Bunsen Burner — provides the hot, non-luminous flame.
• Flame Test Of Chemicals Lab Investigation — a guided flame-test investigation.

See all items in Laboratory Equipment.

Frequently Asked Questions

What flame colour does Lithium Chloride give?
Lithium Chloride gives a bright crimson-red flame when a small sample on a clean wire loop is held in a non-luminous Bunsen flame. The colour resembles strontium, so students often compare both or use a spectroscope to distinguish them.

Why does Lithium Chloride absorb moisture?
Lithium Chloride is strongly hygroscopic because the small lithium ion attracts water molecules strongly. If the container is left open, the powder takes up water from the air and clumps or turns damp, so reseal it immediately after use.

How much Lithium Chloride is in one pack?
One pack of Lithium Chloride (SCI-599/260) holds 100 g of analytical reagent grade salt and comes with an MSDS. Only a few crystals are needed for each flame test, so one pack serves many sessions.

Is Lithium Chloride hazardous?
Lithium Chloride is harmful if swallowed and can irritate skin and eyes. Use gloves and goggles, keep it away from food areas, and follow the handling and disposal guidance in the MSDS supplied with each 100 g pack.

Does Lithium Chloride have an expiry date?
For Lithium Chloride, shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Dry, sealed storage keeps the salt free-flowing.

Strontium Chloride (Product Code: SCI-601/261) is an analytical reagent grade strontium chloride (SrCl₂) used for red flame-colour demonstrations and alkaline earth metal precipitation tests in school and college chemistry laboratories. It is the usual strontium sample in group-trend lessons comparing calcium, strontium and barium, and it comes in a 100 g pack with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Strontium Chloride Used For?

Strontium salts colour a flame deep red, the same effect that gives red colours to fireworks and signal flares, so strontium chloride is a staple of flame-test and emission-spectrum lessons. Because its red resembles lithium's crimson, students compare the two directly and learn to rely on careful observation or a spectroscope.

For group-trend work, strontium chloride solution gives a white precipitate of strontium sulfate with a soluble sulfate and white strontium carbonate with sodium carbonate. Comparing these results with calcium and barium salts shows how sulfate solubility falls down Group 2. The salt can seriously irritate the eyes, so goggles and gloves are essential when weighing it.

What to Specify When Ordering

• Product code SCI-601/261 and the number of 100 g packs.
• Other Group 2 chlorides needed for the comparison set, such as calcium and barium.
• Burners or flame-test apparatus to be included in the same quotation.

Supplier

• Lithium Chloride — crimson flame for comparison with strontium red.
• Strontium Bromide — another strontium salt in the catalogue.
• Sodium Carbonate — precipitates white strontium carbonate.

Browse the Laboratory Equipment category for more.

Frequently Asked Questions

What colour flame does Strontium Chloride produce?
Strontium Chloride produces a deep red flame in a non-luminous Bunsen flame. This is the colour strontium compounds give to red fireworks and flares, which makes the salt popular for flame-test and emission-spectrum lessons.

How can Strontium Chloride be told apart from lithium chloride in a flame test?
Strontium Chloride and lithium chloride both give red flames, so they are hard to separate by eye. A hand spectroscope shows their different line spectra, and a sulfate test also helps, since strontium forms a white sulfate precipitate.

Which precipitation tests use Strontium Chloride?
Strontium Chloride solution gives white strontium sulfate with a soluble sulfate and white strontium carbonate with sodium carbonate. Comparing these with calcium and barium salts illustrates how sulfate solubility decreases down Group 2.

What does the Strontium Chloride SCI-601/261 pack include?

Aluminum Chloride (Product Code: SCI-603/262) is an analytical reagent grade aluminium chloride (AlCl₃) used to show the reactions of aluminium ions, amphoteric hydroxides and salt hydrolysis in school and college chemistry laboratories. The 100 g pack comes with an MSDS; if your method depends on the anhydrous or hydrated form, confirm it with us when you enquire. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Aluminum Chloride Used For?

Adding sodium hydroxide dropwise to aluminium chloride solution gives a white gelatinous precipitate of aluminium hydroxide that dissolves again in excess alkali, the standard demonstration of an amphoteric hydroxide. With ammonia the precipitate forms but does not redissolve, which helps separate aluminium from zinc in salt analysis. The solution is noticeably acidic because hydrated aluminium ions hydrolyse, turning blue litmus red.

Organic chemistry courses know the anhydrous salt as the Lewis acid catalyst for Friedel–Crafts reactions, a use that needs the anhydrous form kept completely dry, so state that requirement when ordering. Anhydrous aluminium chloride reacts vigorously with water and fumes hydrogen chloride in moist air, and its solutions are corrosive, so work in a fume cupboard with gloves and goggles.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, supplies Aluminum Chloride to institutions running inorganic and organic chemistry practicals, and to the dealers who serve them. Because aluminium chloride exists in more than one form, you can ask us to confirm the form of the quoted batch before placing an order. See the ScienceLab profile for more about the company.

Related Laboratory Equipment

Reagents for aluminium ion, amphoteric and hydrolysis experiments:

• Sodium Hydroxide — precipitates aluminium hydroxide and redissolves it in excess.
• Ammonium Hydroxide — precipitates aluminium hydroxide without redissolving it.
• Aluminum Sulfate — another aluminium salt, used in water-clarification demonstrations.
• Aluminum (Powder) — the metal, for comparing element and salt reactions.
• Aluminium Chloride — a separate listing in the Chemistry Lab range.

Further reagents and apparatus are in Laboratory Equipment.

Frequently Asked Questions

Is Aluminum Chloride the same as aluminium chloride?
Yes. Aluminum Chloride is the American spelling of aluminium chloride, AlCl₃. ScienceLab lists it under code SCI-603/262 as a 100 g pack of analytical reagent supplied with an MSDS.

Is Aluminum Chloride SCI-603/262 anhydrous or hydrated?
The Aluminum Chloride SCI-603/262 listing specifies analytical reagent grade and a 100 g pack but not the hydration form. If you need the anhydrous salt, for example as a Friedel–Crafts catalyst, confirm this through the contact page before ordering.

How does Aluminum Chloride demonstrate amphoteric behaviour?
Sodium hydroxide added to Aluminum Chloride solution first forms white gelatinous aluminium hydroxide, which dissolves in excess alkali to give aluminate. Because the hydroxide reacts with both acids and bases, it is a classic amphoteric example.

Why is Aluminum Chloride solution acidic?
Aluminum Chloride solution is acidic because hydrated aluminium ions hydrolyse and release hydrogen ions. A few drops on blue litmus paper turn it red, making the salt useful for teaching hydrolysis of salts formed from a weak base and a strong acid.

What precautions apply to Aluminum Chloride?
Aluminum Chloride is corrosive, and the anhydrous form reacts vigorously with water, releasing hydrogen chloride fumes. Handle it in a fume cupboard with gloves and goggles and keep it sealed. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Potassium Chromate (Product Code: SCI-609/265) is an analytical reagent grade potassium chromate (K₂CrO₄) used as the indicator in Mohr's titration of chloride and as a precipitating reagent for lead, barium and silver ions in college and senior school laboratories. The yellow salt comes in a 100 g pack with an MSDS, and as a chromium(VI) compound it needs careful handling. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Potassium Chromate Used For?

In Mohr's method, a few drops of potassium chromate solution are added to a neutral chloride sample, which is then titrated with standard silver nitrate. White silver chloride precipitates first; once all the chloride is used up, the next drop of silver nitrate forms red-brown silver chromate, marking the end point. The titration is used for chloride in water, salt and food samples in teaching and testing laboratories.

As a precipitating reagent, chromate gives yellow lead chromate, yellow barium chromate and red-brown silver chromate, useful confirmatory tests in salt analysis. Adding acid turns the yellow solution orange as dichromate forms, a simple demonstration of a shifting equilibrium. Chromium(VI) compounds are toxic, carcinogenic and skin sensitisers, so use gloves and goggles, avoid dust and collect waste for hazardous disposal.

Supplier

Schools and colleges setting up volumetric analysis often buy Potassium Chromate together with silver nitrate and burettes, and ScienceLab, the trading name of Jain Scientific Equipments Private Limited, Ambala, supplies all three. Laboratory dealers can also source the indicator for resale to institutions. For company information, visit the ScienceLab profile.

Related Laboratory Equipment

Items used with potassium chromate in Mohr titrations and chromate tests:

• Silver Nitrate — the titrant in Mohr's chloride titration.
• Sodium Chloride — a primary standard for checking the silver nitrate.
• Burette — delivers the titrant drop by drop.
• Potassium Dichromate — the orange partner in the chromate–dichromate equilibrium.
• Lead Nitrate — gives yellow lead chromate with chromate ions.

The complete range is in Laboratory Equipment.

Frequently Asked Questions

Why is Potassium Chromate used as an indicator in Mohr's titration?
Potassium Chromate is used because silver chromate is more soluble than silver chloride under titration conditions, so it forms only after all chloride has precipitated. The first permanent red-brown tint of silver chromate therefore signals the end point.

What conditions does Potassium Chromate need in Mohr's method?
Potassium Chromate works as a Mohr indicator only in neutral or slightly alkaline solution. In acid, chromate converts to dichromate and the end point is lost, while strongly alkaline solutions precipitate silver hydroxide, so adjust samples before titrating.

What pack does Potassium Chromate SCI-609/265 come in?
Potassium Chromate SCI-609/265 is a 100 g pack of analytical reagent grade salt with an MSDS. Indicator solutions need only small amounts of the salt, so one pack supports a large number of titrations.

Is Potassium Chromate hazardous?
Yes. Potassium Chromate contains chromium(VI), which is toxic, carcinogenic and can cause skin allergy. Use it only with gloves, goggles and supervision, avoid raising dust, and dispose of residues as hazardous waste as the MSDS directs.

How should Potassium Chromate be stored?
Store Potassium Chromate in a closed, labelled container in a locked chemical cabinet, away from reducing agents and combustible materials. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

What is the difference between Potassium Chromate and potassium dichromate?
Potassium Chromate contains yellow chromate ions and is used mainly as an indicator and precipitant, whereas potassium dichromate contains orange dichromate ions and serves as an oxidising agent in titrations. Acid converts chromate into dichromate.
