A) Solubility product of \[A{{s}_{2}}{{S}_{3}}\] is less than that of ZnS
B) Enough \[A{{s}^{3+}}\]are present in acidic medium
C) Zinc salt does not ionise in acidic medium
D) Solubility product changes in presence of an acid
Correct Answer: A
Solution :
[a] \[{{K}_{sp}}\] of \[A{{s}_{2}}{{S}_{3}}\] is less than ZnS, In acidic medium ionisation of \[{{H}_{2}}S\] is suppressed (common ion effect) and \[{{K}_{sp}}\] of ZnS does not exceed.You need to login to perform this action.
