उत्तर

Hydrogen peroxide is obtained by the electrolysis of sulphuric acid.

Explanation:

\[\ce{H2O2}\] is obtained by the electrolysis of a cold 50% solution of \[\ce{H2SO4}\].

\[\ce{2H2SO4 -> 2H^{+} + 2HSO^{-}4}\]

\[\begin{array}{cc}
\phantom{}\ce{2H2SO^{-}4 ->[Electrolysis] \underset{\underset{\underset{2HSO^{-}4_{(aq)} + 2H+_{(aq)} + H2O2_{(aq)}}{↓ Hydrolysis}}{Peroxodisulphate}}{HO3SOOSO3H_{(aq)}}}\\
\end{array}\]
