Interpretation Introduction

Interpretation: In the given question, it is to be determined if the ${\text{K}}_{\text{c}}$ value is greater than or less than 1 and the strong acid in the equilibrium mixture has to be identified.

Concept introduction: Strong acid can donate its proton. The equilibrium constant ${\text{K}}_{\text{c}}$ represents the ratio of concentrations of products to the reactants and the extent of the reaction. In the equilibrium mixture of HA and ${\text{B}}^{\text{-}}$ given, stronger acid among HA and HB will dissociate to a greater extent so the mixture will have fewer molecules of the strong acid.
