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