Electrolysis of \(X\) gives \(Y\) at anode. Vacuum distillation of \(Y\) gives \(\mathrm{H}_2 \mathrm{O}_2\). The number of peroxy (O-O) bonds present in \(X\) and \(Y\) respectively are :
- A 1,1
- B 1,2
- C zero, 1
- D zero, zero
Answer & Solution
Correct Answer
(C) zero, 1
Step-by-step Solution
Detailed explanation
A \(30 \%\) solution of hydrogen peroxide can be obtained by the electrolysis of \(50 \%\) sulphuric acid followed by vacuum distillation. The first product of electrolysis is perdisulphuric acid \(\left(\mathrm{H}_2 \mathrm{~S}_2 \mathrm{O}_8\right)\) which reacts with water…
