Abstract
Stannous salts of a non-oxidizing anionic acid, e.g., stannous fluoborate or stannous sulfate, are prepared by reacting metallic tin with a preferably aqueous solution of such acid in the presence of a catalytically effective amount of finely divided catalyst particles, e.g., comprised of a precious metal, said catalyst particles providing hydrogen release at low overvoltages.
