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.
