Stannous Sulphate, SnSO4






Stannous Sulphate, SnSO4, is obtained when the metal or hydrated monoxide is dissolved in dilute sulphuric acid, or when the former is digested with a mixture of one volume of sulphuric acid, two of nitric acid, and three of water. The salt is obtained in white, anhydrous needles on evaporating its solution in a vacuum; 18.8 grams of stannous sulphate dissolve in 100 grams of water at 19° C., and 18.1 grams at 100° C.; its solution is easily hydrolysed with the deposition of a basic salt. The anhydrous salt when heated above 360° C. evolves sulphur dioxide by self-oxidation and reduction, thus:

SnSO4 = SnO2 + SO2.
