Q24 / 180 · KCET 2013 · Chemistry

An example for a neutral buffer is

A
ammonium hydroxide and ammonium chloride
B
acetic acid and sodium acetate
Correct answer
C
acetic acid and ammonium hydroxide
D
citric acid and sodium citrate

Solution

Acetic acid and sodium acetate, citric acid and sodium citrate are acidic buffers, whereas ammonium hydroxide and ammonium chloride is a basic buffer solution. A neutral buffer is a solution of weak acid (acetic acid) and weak base (ammonium hydroxide).

Hence, the correct answer is option: 'C'.
