A saturated solution of H2S in 0.1M HCl at 25°C contains S2− ion concentration of 10−23 mol L−1. The solubility product of some sulphides are CuS = 10−44 , FeS = 10−14 , MnS = 10−15 , CdS = 10−25. If 0.01 M solution of these salts in 1M HCl are saturated with H2S, which of these will be precipitated?
