Question

A dilute aqueous solution of $Na_2SO_4$ is electrolysed using platinum electrodes. The products at the anode and cathode are respectively

A

$O_2, H_2$

B

$S_2O_8^{2-} , Na$

C

$O_2 , Na$

D

$S_2O_8^{2-} , H_2$

Answer

$O_2, H_2$

Explanation

Solution

Electrolysis of aqueous $Na_2SO_4$ gives $H_2 (g)$ at cathode and $O_2(g)$ at anode.
