The following equilibrium is established when hydrogen chloride is dissolved in acetic acid
The set that characterises the conjugate acid-base pairs is
(a) (HCl, CH3COOH) & (CH3COOH2+ ,Cl–)
(b) (HCl, CH3COOH2+) & (CH3COOH,Cl–)
(c) (CH3COOH2+ , HCl) & (Cl–,CH3COOH)
(d) (HCl,Cl–) & (CH3COOH2+, CH3COOH)
