Question

In the classical electrolytic preparation of Hydrogen Peroxide, a 50% solution of Sulphuric acid ($H_2SO_4$) undergoes electrolysis. What specific intermediate compound is generated at the anode, which must subsequently be distilled and hydrolyzed to finally yield $H_2O_2$?

Prashant Kotian · Accepted Answer

Correct answer: B. During the electrolysis of at low temperatures, bisulphate ions () oxidize and dimerize at the anode to form Peroxodisulphuric acid (). This intermediate is then extracted and hydrolyzed with water to produce and .
