H(2)S is passed through the solution in ...

`H_(2)S` is passed through the solution in an acididc medium to precipitate the sulphides of group II cations, but in an alkaline medium to precipitate the sulphides of group IV cations because:

A

the sulphides of group II cations are more soluble than those of group IV cations

B

the sulphides of group II cations have lower solubility products than those of group IV cations

C

the sulphides of group II cations are soluble in an acidic medium, but those of group IV cations are not

D

The sulphides of group IV cations are soluble in an alkaline medium but those of group II cations are not
