Lead Acetate
Lead Acetate (Product Code: SCL-875/180) is lead(II) acetate, a water-soluble lead salt used to detect sulphur and sulphide ions in qualitative analysis in college and school chemistry and biochemistry labs. Paper soaked in its solution blackens in hydrogen sulphide, and in Lassaigne's test it gives a black precipitate when sulphur is present. The 500 gm analytical reagent pack comes with an MSDS and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Lead Acetate Used For?
To make lead acetate paper, strips of filter paper are dipped in a solution of the salt and used while moist: held at the mouth of a test tube, they turn black with lead sulphide when a sulphide salt releases hydrogen sulphide on warming with dilute acid. In the tests for elements in organic compounds, the sodium fusion extract is acidified with acetic acid before lead acetate solution is added, and a black precipitate confirms sulphur. Biochemistry classes use the same reaction to show sulphur-containing amino acids such as cysteine after boiling a protein with alkali.
Teachers also use the solution for precipitation demonstrations in a salt analysis kit for school practicals: potassium iodide gives yellow lead iodide, which dissolves in hot water and reappears as glittering “golden rain” crystals on cooling, and potassium chromate gives yellow lead chromate. Lead compounds are toxic if swallowed or inhaled and are particularly harmful to children and pregnant women, so staff should weigh the salt and everyone should wear gloves. Collect lead residues and used test papers in a labelled waste container rather than washing them down the sink.
Supplier
Lead Acetate is supplied by Jain Scientific Equipments Private Limited, the Ambala-based company whose trading name is ScienceLab. It sources analytical reagents for salt analysis and organic element tests and supplies them to institutions and dealers in India and international markets, so a department can order its reagents and apparatus together. Our company profile has the details.

Frequently Asked Questions
Who supplies Lead Acetate SCL-875/180?
Lead Acetate (SCL-875/180) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. Each 500 gm pack of this analytical reagent is dispatched with an MSDS to institutions and dealers in India and international markets.
How do I make lead acetate paper?
To make lead acetate paper, dissolve a small quantity of Lead Acetate in water, soak strips of filter paper in the solution and use them while still moist. Prepare fresh strips for each session, because dry paper reacts less clearly with hydrogen sulphide.
Why is acetic acid added before lead acetate in Lassaigne's test?
The sodium fusion extract is alkaline. Acidifying it with acetic acid before adding Lead Acetate solution stops white lead hydroxide from forming and hiding the black lead sulphide that confirms sulphur in the organic compound.
What is the shelf life of Lead Acetate?
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 Lead Acetate pack tightly closed in a locked, dry reagent cabinet between practicals.
Is lead acetate suitable for school use?
Lead Acetate can be used in schools in small amounts prepared by staff, because it is toxic. Students should handle only the dilute solution or ready-made test papers, wearing gloves, and wash their hands after the practical.
How should lead acetate waste be disposed of?
Lead Acetate residues and used test papers should be collected in a labelled container and passed to an authorised hazardous waste handler in line with local rules. Lead waste must never be poured down the drain.
