What would happen if, during the electrolysis of copper sulfate solution, the copper anode was replaced with a carbon (inert) anode?
The cathode would dissolve.
Oxygen would be produced at the anode.
The concentration of the copper sulfate would increase.
No reaction would occur.
Explanation
With an inert anode, oxygen gas is produced instead of the anode dissolving
