Electrolysis of concentration H 2 SO 4 arrow H ++ HSO 4- At Cathode 2 H ++2 e - arrow H 2 At Anode 2 HSO 4- arrow underset text Marshall acid stackrel H 2 S 2 O 8 downarrow+2 e -

Q. Electrolysis of $H_{2} S O_{4}$ (conc.) gives the following at anode

$H_{2}$

$O_{2}$

$H_{2} S_{2} O_{3}$

$H_{2} S_{2} O_{8}$

Electrolysis of concentration $H_{2} S O_{4} \to H^{+} + H S O_{4}^{-}$
At Cathode
$2 H^{+} + 2 e^{-} \to H_{2}$
At Anode
$2 H S O_{4}^{-} \to Marshall acid ↓ H_{2} S_{2} O_{8} + 2 e^{-}$
