Reduction occurs at the copper cathode
Oxidation occurs at the copper cathode
Reduction occurs at the anode
Chemical energy is converted to light energy
Because the reduction potential of Cu is highest.
In an electrochemical cell represented as,
Zn | Zn2+(c1) || Cu2+(c2) | Cu
So in this cell,
a.Zn is oxidized
b.Zn is reduced
c.Cu is oxidized
d.Cu is reduced
