<h3>Explanation</h3>A buffer solution contains <em>a weak acid</em> and<em> its conjugate base</em>. The two species shall have a similar concentration in the solution. It's also possible for <em>a weak base</em> and <em>its conjugate acid</em> 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.
