| | Tin(II) oxide Usage And Synthesis |
| 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. |
