A buffer solution contains a weak acid and its conjugate base. The two species shall have a similar concentration in the solution. It's also possible for a weak base and its conjugate acid to form a buffer solution.

The KF solution already contains large number of ions. The objective is to thus find its conjugate acid or base.

contains no proton and is unlikely to be a conjugate acid. Assuming that is a conjugate base. Adding one proton to would produce its conjugate acid.

Therefore is the conjugate acid of . happens to be a weak acid. As a result, combining with would produce a solution with large number of both the weak acid and its conjugate base, which is a buffer solution by definition.
