Lead Carbonate
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.

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.
Supplier
Lead Carbonate is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. It sources inorganic salts such as this for schools, colleges and suppliers in India and international markets, so that reagents and heating glassware can be quoted together.

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.
What should a bulk or tender enquiry for Lead Carbonate include?
A bulk or tender enquiry for Lead Carbonate should state the number of 500 gm packs, the delivery location, any other salts or reagents to be quoted together, and the documents your institution needs. Send it through our contact page.
