`H_(2)S` gas when passed through a solution of cations containing `HCl` precipitates the cations of second group in qualitative analysis but not those belonging to the fourth group. It is becauseA. Presence of HCl decreases the sulphide ion concentrationB. Sulphides of group IV cations are unstable in HClC. Solubility product of group II sulphides is more than that of group IV sulphidesD. Presence of HCl increases the sulphides ion concentration
