A) Presence of \[HCl\] decreases the sulphides ion concentration
B) Presence of HCl increases the sulophide ion concentration
C) Solubility product of group II sulphides is more than that of group IV sulphides
D) Sulphides of group IV cations are in HCl.
Correct Answer: A
Solution :
HCl suppresses ionisation of weakly dissociated \[{{H}_{2}}S\], with the result only the ionic product of the sulphides of group II radicals exceed their corresponding solubility product and hence only these are precipitated.You need to login to perform this action.
