H₂S gas when passed through a solution containing HCl precipitates cations of second group of qualitative analysis but not those of fourth group. It is because:
1
presence of HCl decreases sulphide ion concentration
2
solubility product of group II sulphides is more than that of group IV
3
presence of HCl increases sulphide ion concentration
4
sulphides of group IV cations are unstable
