JEE Advanced · Chemistry · 8. Ionic Equilibrium
Aqueous solutions of \(\mathrm{HNO}_3, \mathrm{KOH}\), \(\mathrm{CH}_3 \mathrm{COOH}\), and \(\mathrm{CH}_3 \mathrm{COONa}\) of identical concentrations are provided. The pair(s) of solutions which form a buffer upon mixing is(are)
- A \(\mathrm{HNO}_3\) and \(\mathrm{CH}_3 \mathrm{COOH}\)
- B \(\mathrm{KOH}\) and \(\mathrm{CH}_3 \mathrm{COONa}\)
- C \(\mathrm{HNO}_3\) and \(\mathrm{CH}_3 \mathrm{COONa}\)
- D \(\mathrm{CH}_3 \mathrm{COOH}\) and \(\mathrm{CH}_3 \mathrm{COONa}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{CH}_3 \mathrm{COOH}\) and \(\mathrm{CH}_3 \mathrm{COONa}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{HNO}_3\) and \(\mathrm{CH}_3 \mathrm{COONa}\) can form buffer if the amount of \(\mathrm{HNO}_3\) is limited. However concentrations are same but the amount can differ with manipulation of volume.
