Q. During electrolysis of aqueous $C u B r_{2}$ using Pt electrode,

$B r_{2} (g)$ is evolved at anode

$C u (s)$ is deposited at cathode

$B r_{2} (g)$ is evolved at anode and $H_{2} (g)$ at cathode

$H_{2} (g)$ is evolved at anode

Aqueous $C u B r_{2}$ :

At cathode: $() C u^{2 +} + 2 e^{-} \to C u$

Q. During electrolysis of aqueous CuBr2​ using Pt electrode,

Br2​(g) is evolved at anode

Cu(s) is deposited at cathode

Br2​(g) is evolved at anode and H2​(g) at cathode

H2​(g) is evolved at anode
