Which of the following mixtures act(s) as buffer solution?
- A \(\mathrm{NaOH}+\mathrm{CH}_3 \mathrm{COOH}\) (1:1 mole ratio)
- B \(\mathrm{NH}_4 \mathrm{OH}+\mathrm{HCl}(2: 1\) mole ratio)
- C \(\mathrm{CH}_3 \mathrm{COOH}+\mathrm{NaOH}(2: 1\) more ratio)
- D \(\mathrm{CH}_3 \mathrm{COOH}+\mathrm{NaOH}(1: 2\) mole ratio)
Answer & Solution
Correct Answer
(C) \(\mathrm{CH}_3 \mathrm{COOH}+\mathrm{NaOH}(2: 1\) more ratio)
Step-by-step Solution
Detailed explanation
Hint : (B) \(\mathrm{NH}_4 \mathrm{OH}+\mathrm{HCl}~(2: 1 \text { mole ratio}) \rightarrow \underset{\large 1 \quad:\quad 1 \atop \large \text{Buffer} \quad \text{buffer}}{\mathrm{NH}_4 \mathrm{Cl}+\mathrm{NH}_4 \mathrm{OH}}\) (C)…
