Question
Which one of the following pairs of the solution is not an acidic buffer?
-
HClO4 and NaClO4
-
CH3COOH and CH3COONa
-
H2CO3 and Na2PO4
-
H2PO4 and Na3PO4
Solution
A.
HClO4 and NaClO4
A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it.
HClO4 and NaClO4 are not an acidic buffer because strong acid with its salt cannot form buffer solution.
