An aqueous solution of hydrogen sulphide shows the equilibrium: `H_(2) S hArr H^(o+)+HS^(ɵ)`  If dilute hydrochloric acid is added to an aqueous solution of `H_(2)S`, without any change in temperature, the  a. The equilibrium constant will change.  b. The concentration `HS^(ɵ)` will increase.  c. The concentration of un-dissociated hydogen sulphide will decrease.  d. The concentration of `HS^(ɵ)` will decrease.
