Question

$H_2{O}_2$ is manufactured these days by:

• A. The electrolysis of $50\%H_{2}S{O}_4$
• B. The action of $H_{2}S{O}_4$ on $N{a}_2{O}_2$
• C. The action of $H_2{O}_2$ on $Ba{O}_2$
• D. Burning hydrogen in excess of oxygen

Answer 1

The correct option is A The electrolysis of $50\%H_{2}S{O}_4$

The electrolysis of 50% sulphuric acid gives per disulphuric acid $H_2{S}_2{O}_8$ which on distillation yields 30% solution of hydrogen peroxide.
