WHAT IS DISSOCIATION OF WEAK ACIDS AND BASESS ? Dissociation of a Weak Acid Consider the dissociation of a weak monobasic acid HA in water, represented by the equation HA+H₂O ⇋ H₃O⁺ + A⁻ Applying the law of chemical equilibrium, the equilibrium constant K c is given by the expression [H₃O⁺][A⁻] K c = ---------------------- ......... (1) [HA] × k The square brackets, as usual, represent concentrations in moles per litre of the entities enclosed therein. Since water is present in large ex...
