Question

$H_{2}O_{2}$ is manufactured these days.

• A. By the action of $H_{2}O_{2}$ on $BaO_{2}$
• B. By the action of $H_{2}SO_{4}$ on $Na_{2}O_{2}$
• C. By electrolysis of 50% $H_{2}SO_{4}$
• D. By burning hydrogen in excess of oxygen

Answer 1

Answer: (C)

By electrolysis of 50% $H_{2}SO_{4}$

Answer 2

Electrolysis of 50% sulphuric acid gives per disulphuric acid $(H_{2}S_{2}O_{8})$ which on distillation yields 30% solution of hydrogen peroxide.
