Lead Carbonate (Product Code: SCL-877/181) is lead(II) carbonate, a white, water-insoluble lead salt used to demonstrate thermal decomposition and carbonate reactions in school and college inorganic chemistry practicals. Colleges also give it as a known sample so students can practise identifying a lead cation and a carbonate anion together. The 500 gm analytical reagent pack arrives with an MSDS and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of the lab chemicals it supplies across India for practical work.

Specifications

What Is Lead Carbonate Used For?

Heated in a dry boiling tube, lead carbonate decomposes into lead(II) oxide and carbon dioxide: the white powder turns yellow, and the gas bubbled through lime water turns it milky. Repeating the experiment with calcium carbonate, which needs far stronger heating before it gives off any gas, shows students how the thermal stability of carbonates differs from metal to metal.

With dilute nitric acid, lead carbonate fizzes and dissolves to give a lead nitrate solution for further tests; hydrochloric and sulphuric acids are poor choices, because they coat the solid with lead chloride or lead sulphate and stall the reaction. As a practice unknown for school and college exam preparation, it rewards careful work: the carbonate shows up as effervescence and a positive lime water test, and the lead is confirmed with potassium iodide or potassium chromate, both of which give yellow precipitates.

Like all lead compounds it is toxic and its fine powder is easily inhaled. Staff should weigh it out in a fume cupboard, students should use gloves and small spatula portions, and residues belong in a labelled lead waste container.

Frequently Asked Questions

Who supplies Lead Carbonate SCL-877/181?
Lead Carbonate (SCL-877/181) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent and dispatches each 500 gm pack with its MSDS to schools, colleges and suppliers in India and international markets.

Why doesn't lead carbonate dissolve in water?
Lead Carbonate is insoluble in water. To bring lead ions into solution for testing, dissolve a small amount in dilute nitric acid, which reacts with the carbonate and leaves a clear lead nitrate solution for the confirmatory tests.

What colour change should students expect when lead carbonate is heated?
When Lead Carbonate is heated, the white powder turns yellow as lead oxide forms, and the carbon dioxide released turns lime water milky. The oxide can look darker while hot and becomes yellow again as it cools.

Is lead carbonate the same as the old white lead pigment?
White lead pigment was traditionally a basic lead carbonate. This Lead Carbonate pack is a laboratory reagent for chemistry practicals and is not for use in paints, cosmetics or anything else outside the lab.

What is the shelf life of Lead Carbonate?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Store the closed Lead Carbonate pack in a locked, dry cabinet away from acids.

Manganese Dioxide (Product Code: SCL-888/187) is manganese(IV) oxide, a black to dark brown solid used as the catalyst for preparing oxygen from hydrogen peroxide in school chemistry labs. Colleges also use it as an oxidising agent in the chlorine preparation and the chloride confirmatory test. This 500 gm analytical reagent pack comes with an MSDS and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier for institutions that stock their own reagents.

Specifications

What Is Manganese Dioxide Used For?

In the oxygen practical, a spatula of manganese dioxide goes into a conical flask and hydrogen peroxide is added through a thistle funnel; the liquid froths, and the oxygen, collected over water in gas jars with standard gas collection apparatus, relights a glowing splint. If the black solid is filtered off, dried and weighed at the end, its mass is unchanged – simple evidence that a catalyst speeds up a reaction without being consumed. Changing the amount of catalyst and timing the volume of gas collected turns the same set-up into an investigation of reaction rate.

Warmed with concentrated hydrochloric acid in a fume cupboard, manganese dioxide oxidises the acid to chlorine; in salt analysis, heating a chloride with manganese dioxide and concentrated sulphuric acid releases chlorine as a confirmatory test for the chloride ion. Students also meet the compound in dry cells, where it surrounds the carbon rod as the depolariser. Avoid breathing the dust, keep it away from strong reducing agents and combustible material, and store the container closed in a dry place.

Supplier

Manganese Dioxide is supplied by Jain Scientific Equipments Private Limited under the ScienceLab name, from Ambala in Haryana, India. The company sources consumable reagents like this catalyst and supplies them to schools, colleges and trade customers in India and international markets, alongside the glassware used for gas preparation.

Frequently Asked Questions

Who supplies Manganese Dioxide SCL-888/187?
Manganese Dioxide (SCL-888/187) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. Each 500 gm pack of this analytical reagent is sent with an MSDS to schools, colleges and trade customers in India and international markets.

Is manganese dioxide used up in the oxygen experiment?
No. Manganese Dioxide acts as a catalyst, so it can be filtered off, rinsed with water, dried and used again. A small spatula-full serves each flask, which means one 500 gm pack lasts through many classes.

Why does the oxygen reaction with manganese dioxide sometimes froth over?
Too much Manganese Dioxide or a strong peroxide solution makes the decomposition very fast, so the flask froths over. Add the peroxide gradually through the thistle funnel and start with small quantities of both reagents.

What is the shelf life of Manganese Dioxide?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Manganese Dioxide in its closed container in a dry place, away from reducing agents and combustible material.

Is manganese dioxide safe for students to handle?
Students wearing gloves can handle small quantities of Manganese Dioxide, but the dust is harmful if inhaled or swallowed. The chlorine preparation with concentrated hydrochloric acid should be done only by staff in a fume cupboard.

Can batch analysis data be supplied with Manganese Dioxide?
An MSDS comes with every pack of Manganese Dioxide. If you need batch-specific analysis data for records or a tender, ask through our contact page before placing the order and we will tell you what is available.

Mercuric Chloride (Product Code: SCL-890/188) is mercury(II) chloride, a highly toxic inorganic salt used for the tin(II) confirmatory test and for preparing Nessler's reagent in college and university chemistry labs. The small 100 gm analytical reagent pack, sent with an MSDS, suits a chemical that is used a few drops at a time and kept under strict control. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to institutions with trained laboratory staff.

Specifications

What Is Mercuric Chloride Used For?

In the analysis of Group II cations, a few drops of mercuric chloride solution added to a tin(II) solution give a silky white precipitate of mercurous chloride, which turns grey or black as more tin(II) reduces it to mercury – a clear confirmatory test for stannous ions. Laboratories that make their own Nessler's reagent start from mercuric chloride and potassium iodide in alkaline solution; the finished reagent reveals ammonia and ammonium ions in water analysis as a yellow to brown colour. Adding potassium iodide solution drop by drop to mercuric chloride also demonstrates a scarlet precipitate of mercury(II) iodide that dissolves again in excess iodide.

Mercuric chloride is highly toxic if swallowed, if its dust is inhaled or if it is absorbed through the skin, and it damages the kidneys and the environment. For that reason many schools buy ready-made Nessler's reagent rather than keeping the solid. Where it is held, keep it in a locked chemistry reagent cabinet with a usage log, weigh it only inside a fume cupboard wearing nitrile gloves and eye protection, and collect every residue as mercury waste for a licensed disposal service.

Supplier

Mercuric Chloride is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, and sources restricted reagents like this for institutional laboratories. For vendor registration, the supplying company's details are CIN U29309HR2020PTC087597 (Ministry of Corporate Affairs) and GSTIN 06AAECJ8618A1ZT. Details are on our company profile.

Methanol (Product Code: SCL-892/189) is methyl alcohol, the simplest alcohol, used as a solvent and reactant in school and college chemistry practicals such as the borate flame test and methyl ester preparation. Biology labs also use it to fix smears before staining. This 500 ml analytical reagent bottle carries an MSDS and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India for solvents, reagents and glassware.

Specifications

What Is Methanol Used For?

For the borate test, a little of the suspected salt is mixed with methanol and a few drops of concentrated sulphuric acid in a china dish and the vapour is lit: a green-edged flame from methyl borate confirms the borate ion. In organic practicals, methanol warmed with salicylic acid and a little concentrated sulphuric acid gives methyl salicylate, easily recognised by its oil-of-wintergreen smell. It is also used for recrystallising organic solids and in the solvent mixture of a paper chromatography kit for school and college practicals.

Methanol is poisonous: swallowing even a small amount can cause blindness or death, and the vapour and skin contact are harmful too. It burns with a pale, almost invisible flame, so keep it well away from burners, dispense only the volume needed, and never leave the bottle open on the bench. Store it closed in a cool, well-ventilated flammables cupboard, keep a solvent spill kit to hand, and label it clearly so it is never mistaken for ethanol.

Supplier

Methanol is supplied by Jain Scientific Equipments Private Limited of Ambala, Haryana, India, which trades as ScienceLab. The company sources solvents and reagents like this one for institutions and dealers in India and international markets, so a practical programme can be equipped through a single order. Company information is on the company profile page.

Methyl Orange (Product Code: SCL-894/190) is an acid-base indicator used to show the end point when a strong acid is titrated against sodium carbonate or another weak base in school and college chemistry labs. It is red in acidic solution and yellow in neutral or alkaline solution, and comes as a liquid in a 500 ml analytical reagent bottle with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a staple of any acid base indicator kit.

Specifications

What Is Methyl Orange Used For?

In the standard volumetric exercise, a pipetted volume of sodium carbonate solution is placed in a conical flask with two or three drops of methyl orange and titrated with hydrochloric acid from a burette until the yellow colour just turns orange. The same pairing is used to standardise the acid before it goes into a titration kit for school and college students, and to estimate the alkalinity of water samples.

Methyl orange is not suitable when a weak acid such as acetic or oxalic acid is titrated against sodium hydroxide, because its colour changes well before the equivalence point; phenolphthalein is used for those titrations instead. Only a few drops are needed per titration, so transfer a small working quantity to a dropping bottle for the bench and keep the stock bottle closed and out of direct sunlight. The dye stains skin and clothing, so rinse splashes promptly and wipe drips from burette tips and bench surfaces.

Supplier

Methyl Orange is supplied by Jain Scientific Equipments Private Limited, an Ambala, Haryana company trading as ScienceLab. It sources indicators and other titration reagents for schools, colleges and distributors in India and international markets, so they can be quoted with burettes and flasks in one enquiry. You can read about the company on our company profile.

Reagents and glassware for an acid-base titration using methyl orange:

• Sodium Carbonate — the standard base titrated against acid with this indicator
• Hydrochloric Acid Dilute — the acid most often titrated with methyl orange
• Phenolphthalein Solution — the companion indicator for weak-acid titrations
• Burette — delivers the acid in measured amounts up to the end point
• Conical Flask — holds the base and indicator while the titration is carried out

More indicators and volumetric glassware are listed in the Chemistry Lab category.

Frequently Asked Questions

Who supplies Methyl Orange SCL-894/190?
Methyl Orange (SCL-894/190) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The indicator is sent as a liquid in a 500 ml analytical reagent bottle, with an MSDS, to schools, colleges and distributors in India and international markets.

What colour change marks the end point with methyl orange?
When acid is added to a base containing Methyl Orange, the solution changes from yellow to orange; take the first permanent orange tint as the end point. If it turns fully red, the end point has been overshot.

When should phenolphthalein be used instead of methyl orange?
Phenolphthalein replaces Methyl Orange when a weak acid, such as acetic or oxalic acid, is titrated against a strong base. Methyl Orange suits titrations of a strong acid against a strong or weak base, such as hydrochloric acid against sodium carbonate.

What concentration is the Methyl Orange indicator?
Methyl Orange is supplied as a liquid in a 500 ml bottle, but the concentration is not stated in this listing. If your practical manual specifies one, check with us through the contact page before ordering.

What is the shelf life of Methyl Orange?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep the Methyl Orange stock bottle tightly closed and away from direct sunlight between practicals.

How many drops of methyl orange should be used?
Usually two or three drops of Methyl Orange are enough for each titration. Using the same number every time keeps the end-point colour consistent across a set of readings and makes the results easier to compare.

Methylated Spirit (Product Code: SCL-896/191) is denatured ethyl alcohol used as spirit lamp fuel and as a cleaning and rinsing solvent in school, college and teaching laboratories. It is packed in a 5 litre stock container of analytical reagent grade with an MSDS, suiting labs that heat and clean glassware every working day. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a standing item on the lab consumables list of institutions across the country.

Specifications

What Is Methylated Spirit Used For?

In the school laboratory, methylated spirit is the usual fuel for glass spirit lamps, giving a steady flame for gentle heating of test tubes and for flaming inoculating loops where no gas line is available. It is also used to wipe down benches, to rinse the last traces of water from freshly washed glassware so that it dries quickly, and to dissolve grease, resin and marker ink that water alone will not remove.

The 5 litre container is a stock size, so decant a working quantity into a labelled wash bottle and refill lamps from that smaller bottle instead of pouring from the large can near students. Fill lamps only when they are cold and unlit, keep the container closed and away from flames and sunlight, and read the MSDS before first use. Schools planning their school chemistry lab equipment in India usually keep methylated spirit on the standing consumables list next to burners and spare wicks.

Molisch Reagent (Product Code: SCL-898/192) is a ready-to-use test reagent used for the Molisch test, the general screening test that shows whether a sample contains carbohydrate, in school, college and food or biology teaching labs. It comes in a 125 ml bottle of analytical reagent grade with an MSDS, enough for many small-scale biomolecule tests. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its range as a chemistry consumables supplier in India.

Specifications

What Is Molisch Reagent Used For?

Students add a few drops of Molisch reagent to the test solution in a clean test tube, mix gently, and then let concentrated sulphuric acid run slowly down the inside of the tilted tube so that it settles as a separate layer at the bottom. The acid dehydrates any carbohydrate present, and the products react with the reagent to form a violet ring at the junction of the two layers. Sugars such as glucose and sucrose and polysaccharides such as starch all give a positive result, which is why the test is used first, before more specific tests for reducing sugars or starch.

Because concentrated acid is involved, the acid layering step should be demonstrated by the teacher or done by students wearing goggles and gloves, with the tube held away from the face. Record the result against a blank of distilled water for comparison. A single 125 ml bottle covers many small-scale tests, and it fits neatly into the reagent rack of a school biology lab set up for food-testing practicals.

Supplier

Molisch Reagent is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, and sources test reagents for schools, colleges and dealers in India and international markets.

Is sulphuric acid included with Molisch Reagent?
No. The pack contains 125 ml of Molisch Reagent only; the concentrated sulphuric acid needed to form the violet ring is listed separately and can be added to the same enquiry through the enquiry cart.

Can the Molisch test tell glucose from starch?
No. The test with Molisch Reagent is a general test that responds to carbohydrates as a group. Use Benedict's or iodine tests afterwards to distinguish reducing sugars from starch in the same food sample.

What is the shelf life of Molisch Reagent?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep the Molisch Reagent bottle tightly capped, upright and away from heat and direct light.

Beta Naphthol (Product Code: SCL-901/0193), also called 2-naphthol, is an organic reagent used as the coupling component to prepare azo dyes and to confirm primary aromatic amines in senior secondary and college organic chemistry practicals. This 500 gm pack is analytical reagent grade and arrives with an MSDS for dye-chemistry teaching labs. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India for schools and colleges.

Specifications

What Is Beta Naphthol Used For?

The classic practical is the azo dye test for an aromatic amino group. Aniline is dissolved in hydrochloric acid, cooled in an ice bath and diazotised with a cold sodium nitrite solution; the resulting diazonium salt is then poured into beta naphthol dissolved in sodium hydroxide solution. An orange-red to scarlet precipitate of the azo dye forms almost at once, which both confirms the amine and demonstrates how synthetic dyes are built by coupling reactions.

Keep the ice bath cold throughout, because diazonium salts decompose on warming and the colour will then be weak. Weigh the solid on a clean spatula, avoid inhaling dust, and wear gloves, as the compound irritates skin. Store the bottle closed and away from light, since the solid tends to darken on long exposure to air and light.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, an Ambala, Haryana company that supplies Beta Naphthol and other organic reagents to schools, colleges and dealers in India and international markets. Ordering the naphthol together with the aniline, nitrite and glassware keeps the complete azo dye practical in one enquiry. Read more on the company profile page.

The other reagents and apparatus used in the azo dye practical:

• Aniline — the primary aromatic amine that is diazotised before coupling
• Sodium Nitrite — generates nitrous acid for the diazotisation step
• Sodium Hydroxide — used to dissolve beta naphthol as its alkaline solution
• Concentrated Hydrochloric Acid (C.P grade) — dissolves aniline as its hydrochloride
• Glass Beaker — for the cold mixing and precipitation steps

See the complete Chemistry Lab category for further reagents.

Frequently Asked Questions

Who supplies Beta Naphthol SCL-901/0193?
Beta Naphthol (SCL-901/0193) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent and dispatches each 500 gm pack with its MSDS to schools, colleges and dealers in India and international markets.

Is Beta Naphthol the same product that was listed as Beta Napthol?

Why is Beta Naphthol dissolved in sodium hydroxide before use?
Beta Naphthol dissolves poorly in water but readily in dilute sodium hydroxide, and this alkaline form is the one that couples quickly with the cold diazonium salt to give the orange-red azo dye.

What is the shelf life of Beta Naphthol?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Beta Naphthol tightly closed, dry and out of direct light to limit discolouration of the solid.

Can you quote a specific purity figure for Beta Naphthol?
Beta Naphthol is listed as analytical reagent grade. For an exact assay or a batch document, ask through the contact page before ordering and we will confirm what is available for the current lot.

How much Beta Naphthol is in one pack?
One pack contains 500 gm of Beta Naphthol as a solid. Only small amounts are needed for each azo dye test, so a single pack serves many student batches when it is kept closed between practicals.
