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 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.

A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.

Reduction occurs at the cathode in an electrolytic cell.
In an electrolytic cell, the anode is positive.
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.
In an electrolytic cell, the anode is designated as positive.
