$50 \% \ H_2 SO_4$

Vedclass · Answer

(B) $H_2 O_2$ is obtained by the electrolysis of a cold $50 \%$ solution of $H_2 SO_4$. The electrolysis of $HSO_4^-$ ions at high current density leads to the formation of peroxodisulphate $(H_2 S_2 O_8)$,which upon hydrolysis yields hydrogen peroxide. The reaction is: $2 HSO_4^- \xrightarrow{	ext{Electrolysis}} HO_3 SOOSO_3 H + 2 e^-$. $HO_3 SOOSO_3 H + 2 H_2 O ightarrow 2 H_2 SO_4 + H_2 O_2$.

Which of the following solutions produces $H_2 O_2$ on electrolysis?
