The electrode where reduction occurs.

Cu(s)
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
The cathode
Ni2+
In an electrolytic cell, the cathode is the electrode that gets heavier. This occurs because reduction reactions take place at the cathode, where cations from the electrolyte gain electrons and deposit onto the electrode, increasing its mass. Conversely, at the anode, oxidation reactions cause the electrode to lose mass as material is oxidized and released into the solution.

The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
In an electrolytic cell, the anode typically gets heavier due to the oxidation reactions occurring there, where metal ions dissolve into the solution and subsequently deposit on the cathode. Conversely, the cathode gains mass as the metal ions in the solution are reduced and deposit onto its surface. This transfer of mass results in a net increase in weight at the cathode while the anode experiences a decrease.

In Chemistry an anodic is an electroplating cell in an electrode in which it gets a negative charge as in a negative charge from a chemical reaction in a battery.
