Answer & Solution

Correct Answer

(D) \(HClO_4\) एंव \(NaClO_4\)

Step-by-step Solution

Detailed explanation

A buffer solution is one which resists changes in \(\mathrm{pH}\) when small quantities of an acid or an alkali are added to it. \(\mathrm{HClO}_{4}\) and \(\mathrm{NaClO}_{4}\) are not an acidic buffer because strong acid with its salt cannot form buffer solution.
