Tin-Grain (Granules)
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.

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.

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?
Colleges can add Tin-Grain (Granules), nitrobenzene and hydrochloric acid to the enquiry cart or list them on the contact page. Jain Scientific Equipments Pvt Ltd (ScienceLab) will quote the set for delivery in India and international markets.
Request a Quote
Send the number of 100 g packs of Tin-Grain (Granules) and your delivery address via the contact page, or add it to the enquiry cart with nitrobenzene and hydrochloric acid for the aniline preparation. We will confirm availability and send a quotation.
