An acidic buffer solution can be prepared by mixing the solutions of
(a) sodium acetate and acetic acid
(b) ammonium chloride and ammonium hydroxide
(c) sulphuric acid and sodium sulphate
(d) sodium chloride and sodium hydroxide
The correct option (a) sodium acetate and acetic acid
Explanation:
Acidic buffer is a mixture of weak acid and its salt with strong base (or its conjugate base). Acetic acid (CH3COOH)is a weak acid and sodium acetate (CH3COONa) is its salt with strong base, thus mixture of acetic acid and sodium acetate forms acidic buffer solution.
