Question

H₂O₂ can be produced by successive reactions

2NH₄HSO₄ →H₂ + (NH₄)₂S₂O₈

The first reaction is an electrolytic reaction and second is steam distillation. What amount of current would have to be used in first reaction to produce enough (NH₄)2S₂O₈ to yield 100 gm H₂O₂ per hour? (Assume current efficiency is 75%)

Answer 1

Given

Since efficiency is 60% hence mass of (NH₄)₂ S₂O₈ required will be

Equivalent mass of (NH₄)₂S₂O₈ may be calculated
