What is Stannous sulfate?

Chemical properties

Stannous sulfate is a white solid that can absorb enough moisture from the air to become fully dissolved, forming an aqueous solution; this property is known as deliquescence.

The Uses of Stannous sulfate

In tin plating; preparation of stannous salts.

The Uses of Stannous sulfate

Stannous sulfate is used in tin plating baths and it is a precursor for tin metal.

Hazard

Toxic material.

Flammability and Explosibility

Non flammable

Preparation

Stannous sulfate can be prepared by a displacement reaction between metallic tin and copper(II) sulfate:

Sn (s) + CuSO4(aq) → Cu (s) + SnSO4(aq)
