Tin Metal Powder - Sn - 63 micron - 100 g

Chemical formula: Sn

Synonyms: tin superfine powder

Amount: 100 g

Appearance and odour: heavy dark grey powder without any appreciable odour

Grade: 99.91 %, 63 micron, 230 Mesh

Packaging: professional wide necked, white HDPE bottle with blue conical seal cap and tamper ring. Labelled. Bottle and cap are UN approved and reusable.

Description and uses: superfine elemental tin powder.

Ideal for various organic and inorganic tin compound preparations.

With anhydrous HCl gas, anhydrous SnCl2 (stannous chloride) is formed. With hydrochloric acid, hydrated stannous chloride (SnCl2.2H2O) results.

With dry chlorine gas (Cl2) it unites to form anhydrous stannic chloride (SnCl4).

Tin metal reacts very vigorously with mixtures of hydrochloric acid and nitric acid (so called Aqua Regis) to form a solution of H2SnCl6. Caution: due to the fineness of this grade only small amounts of this powder should be added one at a time to well stirred Aqua Regis because the reaction can be violent and lead to boil-overs.

Tin metal is a mild reduction agent.
