Which of the following does not form a buffer solution?
- A \(\mathrm{NH}_3+\mathrm{HCl}(2: 1\) mole ratio \()\)
- B \(\mathrm{CH}_3 \mathrm{CO}_2 \mathrm{H}+\mathrm{NaOH}\) (2:1 mole ratio)
- C \(\mathrm{NaOH}+\mathrm{CH}_3 \mathrm{COOH}\) (1:1 mole ratio)
- D \(\mathrm{NH}_4 \mathrm{Cl}+\mathrm{NH}_3(1: 1\) mole ratio \()\)
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…
