A buffer solution is one which resist changes in $\mathrm{pH}$ when small quantities of an acid or an alkali are added to it. A solution of $\mathrm{HClO}_4$ and $\mathrm{NaClO}_4$ is not an acid buffer because strong acid with its salt cannot form a buffer solution.

Which buffer solution comprising of the following has its $\mathrm{pH}$ value greater than 7 ?
The $\mathrm{pH}$ value of basic buffer is always greater than 7. Among the given options, $\mathrm{NH}_4 \mathrm{OH}+\mathrm{NH}_4 \mathrm{Cl}$ is the only mixture which consists of a mixture of a weak base and its conjugated salt and thus, has a $\mathrm{pH}$ greater than 7. Basic buffer solution: A basic buffer solution consists of a mixture of a weak base and its salt with strong acid. the best known example in a mixture of $\mathrm{NH}_4 \mathrm{OH}$ and $\mathrm{NH}_4 \mathrm{Cl}$.
