Answer:
The oxidation occur on the zinc electrode.
Explanation:
An electrochemical cell is a device in which chemical energy produced during reaction is converted into electrical energy. in these type of cells oxidation occurs at anode and reduction occurs at cathode.
At cathode :(reduction)
[tex]Cu^{2+}+2e^-\rightarrow Cu[/tex]
At anode: (oxidation)
[tex]Zn^{2+}\rightarrow Zn^{2+}+2e^-[/tex]
