\(\mathrm{KMnO}_4\) oxidises \(\mathrm{C}_2 \mathrm{H}_2 \mathrm{O}_4\) to form \(\mathrm{CO}_2\). In which of the following, the reaction will be faster?

  1. A Aq. HCl solution
  2. B Aq. \(\mathrm{NaOH}\) solution
  3. C Aq. \(\mathrm{NaCl}\) solution
  4. D Aq. \(\mathrm{NaHCO}_3\) solution
Verified Solution

Answer & Solution

Correct Answer

(A) Aq. HCl solution

Step-by-step Solution

Detailed explanation

The reaction will faster in aqueous \(\mathrm{HCl}\) because chlorine ion present in \(\mathrm{HCl}\) get oxidised into chlorine gas by \(\mathrm{KMnO}_4\), so the amount of \(\mathrm{KMnO}_4\) will be more as it oxidises both oxalic acid and chlorine ion when \(\mathrm{HCl}\)…
