Question

The Ka constant of a weak acid always deals with the weak acid dissociating in water to form H3O+ and the conjugate base of the weak acid. Write equilibrium reactions of the following weak acids in water and then write the corresponding Ka expressions in terms of concentrations of the weak acid, its conjugate base, and the conjugate acid of water, H3O+.
