TIN(II) OXIDE Chemical Properties,Usage,Production
Physical Properties
Bluish-black powder; tetragonal crystals; density 6.45 g/cm3; decomposes at 1,080°C; insoluble in water; dissolves in acids to form Sn2+ and in base to form stannite ion, Sn(OH)3–.
Uses
Tin(II) oxide is a reducing agent; and is used in preparing other tin(II) salts. Also, it is used to make soft abrasive putty powder.
Preparation
Tin(II) oxide is prepared by heating tin(II) hydroxide. The latter is obtained as a white precipitate by reacting Sn2+ ions with hydroxide ions:
Sn2+(aq) + 2OH¯(aq) → Sn(OH)2 (s)
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.
Uses
Reducing agent; preparation of stannous salts.
Uses
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.
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.
