The following equilibrium exists in an aqueous solution of hydrogen sulphide `H_(2)S hArr H^(+) + HS^(-)` If dilute HCl is added to an aqueous solution of `H_(2)S` without any change in temperatureA. The equilibrium constant will changeB. The concentration of `HS^(-)` will increaseC. The concentration of undissociated `H_(2)S` will decreaseD. The concentration of `HS^(-)` will decrease |

Answer» Correct Answer - D In aqueous solution following euilibrium the dilute HCl `H_(2)S hArr H^(+) + HS^(-)` While adding the dilute HCl solution `(HCl hArr H^(+) + Cl^(-))` equilibrium is shift to the left side in `H_(2)S hArr H^(+) + HS^(-)`. |
