Vedclass · Answer

(C) The electrolytic preparation of $H_2O_2$ involves the electrolysis of $50\%$ $H_2SO_4$ solution. At the anode,the oxidation of $HSO_4^-$ ions takes place to form peroxodisulfuric acid $(H_2S_2O_8)$,which is then hydrolyzed to produce $H_2O_2$. Hydrogen gas is liberated at the cathode,not the anode. Therefore,the statement that hydrogen is liberated at the anode is incorrect.

Which of the following is $NOT$ true for the electrolytic preparation of $H_2O_2$?
