Which of the following does not form a buffer solution?

  1. A \(\mathrm{NH}_3+\mathrm{HCl}(2: 1\) mole ratio \()\)
  2. B \(\mathrm{CH}_3 \mathrm{CO}_2 \mathrm{H}+\mathrm{NaOH}\) (2:1 mole ratio)
  3. C \(\mathrm{NaOH}+\mathrm{CH}_3 \mathrm{COOH}\) (1:1 mole ratio)
  4. D \(\mathrm{NH}_4 \mathrm{Cl}+\mathrm{NH}_3(1: 1\) mole ratio \()\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\mathrm{NaOH}+\mathrm{CH}_3 \mathrm{COOH}\) (1:1 mole ratio)

Step-by-step Solution

Detailed explanation

A buffer solution is formed when we have a mixture of a weak acid or base and its corresponding salt with a strong base or acid. A \(1: 1\) mixture of \(\mathrm{NaOH}\) and \(\mathrm{CH}_3 \mathrm{COOH}\) will have unequal concentrations of \(\mathrm{CH}_3 \mathrm{COOH}\) and…
