H₂S gas when passed through a solution of cations containing HCl precipitates the cations of second group of qualitative analysis but not those belonging to the fourth group. It is because

presence of HCl decreases the sulphide ion concentration

solubility product of group II sulphides is more than that of group IV sulphates

presence of HCl increases the sulphide ion concentration

sulphides of group IV cations are unstable in HCl.
