A) concentration of\[H{{S}^{-}}\]will increase
B) concentration of\[H{{S}^{-}}\]will decrease
C) dissociation of\[{{H}_{2}}S\]will increase
D) dissociation of\[{{H}_{2}}S\]will stop
Correct Answer: B
Solution :
\[{{H}_{2}}S{{H}^{+}}+H{{S}^{-}}\] On adding\[HCl\] \[HCl\underset{common-ion}{\mathop{{{H}^{+}}+C{{l}^{-}}}}\,\] Hence, on adding\[HCl\]at equilibrium the concentration of\[H{{S}^{-}}\]ion will decrease due to common-ion effect.You need to login to perform this action.
