The electrode connected to the positive terminal (anode) typically gets heavier in an electrolytic cell as ions from the electrolyte are attracted to it and deposit on its surface. This process is known as electroplating, where the anode loses mass as it releases ions into the electrolytic solution.

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 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.

As a battery discharges, the products of the chemical reaction inside the cell accumulate, causing the cell to get heavier due to the increase in mass. Additionally, if the battery is recharging, the reverse chemical reaction occurs, leading to the accumulation of reactants and an increase in weight.
In general, positive ions (cations) are attracted to the cathode (negative electrode) and negative ions (anions) are attracted to the anode (positive electrode) in an electrolytic cell. This is because the cathode gains electrons and the anode loses electrons during electrolysis.
