An example for a neutral buffer is

Options

  1. Aammonium hydroxide and ammonium chloride
  2. Bacetic acid and sodium acetate
  3. Cacetic acid and ammonium hydroxide
  4. Dcitric acid and sodium citrate

Correct answer

C. acetic acid and ammonium hydroxide

Step-by-step 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).
