Tin ( II) sulfate is a chemical compound made ​​of tin, sulfur, and oxygen with the chemical formula SnSO4.

Production and representation

Tin ( II) sulfate can be obtained by the reaction of copper ( II) sulfate with amalgamated tin.

It can also be prepared by reaction of tin or tin ( II) oxide with sulfuric acid.

Properties

Tin ( II ) sulfate is a colorless, non-flammable, easily soluble in water solid. It is stable to about 360 ° C, and then decomposes to sulfur dioxide and tin ( IV) oxide. Its aqueous solution is strongly acidic and decomposes soon with precipitation of a basic sulphate. In air, it oxidizes very quickly.

Use

In the construction industry tin sulfate is used as an adjuvant to reduce chromate in cement. Furthermore, it is used as an electrolyte in electroplating, and as an additive for electrolytes in lead accumulators.
