Which one of the following mixture does not act as a buffer solution?

A
Boric acid and borax.
B
Sodium phosphate & disodium hydrogen phosphate.
C
Sodium propionate and propionic acid.
D
Sodium acetate and sodium propionate.

Answer

Sodium acetate and sodium propionate.

Explanation:

An acidic buffer contains equimolar quantities of weak acid and its salt with strong base. A basic buffer contains equinolar quantities of weak base and its salt with strong acid. Sodium acetate is a salt with strong base but sodium propionate is not weak acid, it is also a salt.
