A) The equilibrium constant will change
B) The concentration of \[H{{S}^{-}}\]will increase
C) The concentration of undissociated \[{{H}_{2}}S\] will decrease
D) The concentration of \[H{{S}^{-}}\]will decrease
Correct Answer: D
Solution :
In aqueous solution following euilibrium is exist. \[{{H}_{2}}S\]⇌\[{{H}^{+}}+H{{S}^{-}}\] While adding the dilute HCl solution \[(HCl\]⇌\[{{H}^{+}}+C{{l}^{-}})\] equilibrium is shift to the left side in \[{{H}_{2}}S\]⇌\[{{H}^{+}}+H{{S}^{-}}\]You need to login to perform this action.
