Stannous Sulfate is a white to slightly yellow, heavy crystalline powder. When dissolved in a 5% Sulfuric Acid Solution, a clear solution is obtained. Gradual hydrolysis occurs over a period of time with the formation of insoluble tin compounds.
Stannous (II) sulphate is a chemical compound. It 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. It can be prepared by a displacement reaction between metallic tin and copper(II) sulfate.
