In pure water the solubility of Na 2 S is said to be 18.06 g per 100 g H 2 O and for Ba 2 S it is 7.28 g. In the case of some less-basic elements (e.g. Al 2 S 3 , Cr 2 S 3 ) hydrolysis is complete and action of H 2 S on solutions of the metal cation results in the precipitation of the hydroxide; likewise these sulfides (and SiS 2 , etc.) react
