tin dihydroxide

Chemical Properties

Stannous Oxide Hydrate. Stannous oxide hydrate, SnO·H2O (sometimes erroneously called stannous hydroxide or stannous acid), mol wt 152.7, is obtained as a white amorphous crystalline product on treatment of stannous chloride solutions with alkali. It dissolves in alkali solutions, forming stannites. The stannite solutions, which decompose readily to alkali-metal stannates and tin, have been used industrially for immersion tinning.
