निम्न किन अभिक्रियाओ में \(H _{2} O _{2}\) एक अपचायक का काम करता है?

  1. A \(H_2O_2 + 2H^++ 2e^- \rightarrow 2H_2O\)
  2. B \(H_2O_2 +2e^-\rightarrow  O_2 +2H^+\)
  3. C \(H_2O_2 +2e^-\rightarrow 2OH^-\)
  4. D \(H_2O_2+2OH^- \, -2e^- \rightarrow O_2+2H_2O\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(H_2O_2+2OH^- \, -2e^- \rightarrow O_2+2H_2O\)

Step-by-step Solution

Detailed explanation

\(\mathrm{H}_{2} \mathrm{O}_{2}+2 \mathrm{OH}^{-}-2 \mathrm{e} \rightarrow \mathrm{O}_{2}+2 \mathrm{H}_{2} \mathrm{O}\) A molecule of \(\mathrm{H}_{2} \mathrm{O}_{2}\) loses hydrogen and is oxidized.
