When aqueous solution of cupric bromide is electrolyzed the product obtained at cathode and at anode will be respectively :
Options:
Answer:
D
Solution:
In the electrolysis of aqueous CuBr₂, Cu²⁺ ions are reduced at the cathode to form Cu metal, as Cu²⁺ has a higher reduction potential than H₂O. At the anode, Br⁻ ions are oxidized to Br₂, as Br⁻ has a lower oxidation potential than H₂O.
Cathode (reduction):
Anode (oxidation):
Therefore, the products are Cu at the cathode and Br₂ at the anode.
