What is TIN(II) OXIDE?

Chemical properties

black crystals with a characteristic odour. Tin oxide is insoluble in water but soluble in acids and alkalis and slightly soluble in ammonium chloride. Tin oxide is incompatible with acids and/or alkalis.

The Uses of TIN(II) OXIDE

Tin(II) oxide is used as reducing agent, soft abrasive, and in preparation of stannous salts. It is used in the manufacture of copper ruby glass, and for illumination with UV light.

The Uses of TIN(II) OXIDE

Reducing agent; preparation of stannous salts.

General Description

Brownish-black powder or black to blue-black crystalline solid. Mp: 1080°C (decomposes); density: 6.45 g cm-3. Insoluble in water.

Reactivity Profile

TIN(II) OXIDE is a reducing agent. Unstable in air due to slow oxidation to tin(IV) oxide. At 300°C this oxidation proceeds incandescently. Incompatible with strong oxidizing agents. Reacts with acids and with strong bases.
