Q. During electrolysis of aqueous $CuBr _2$ using Pt electrode,
Electrochemistry
A
$Br _2( g )$ is evolved at anode
B
$Cu (s)$ is deposited at cathode
C
$Br _2( g )$ is evolved at anode and $H _2( g )$ at cathode
D
$H _2( g )$ is evolved at anode
Solution:
Aqueous $CuBr_2$:
At cathode: $(\sqrt{\sqrt{ }}) Cu ^{2+}+2 e^{-} \rightarrow Cu$
