(ii) The Cu2+ ions are attracted to the negative electrode, where they are reduced to produce copper atoms.
1 answer:
Electrolyte for the electrolysis is copper(II) sulfate
CuSO₄ = Cu²⁺ + SO₄²⁻
the reaction at the negative electrode
(cathode -) Cu²⁺ + 2e⁻ = Cu⁰
and...
(anode +) 2H₂O - 4e⁻ = O₂ + 4H⁺
