Ni2+
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 a galvanic cell with silver and nickel electrodes, the nickel electrode will be oxidized. Oxidation occurs at the anode, where electrons are released as nickel atoms lose electrons and form nickel ions. Silver ions from the other electrode will capture these electrons as the reduction reaction occurs at the cathode.

In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.
In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
The voltage of an electrolytic cell with nickel and copper electrodes depends on the specific electrolyte used and the concentration of the solutions. Typically, nickel and copper electrodes can have a cell potential of around 0.3 to 0.5 volts when considering their standard reduction potentials. However, in an electrolytic cell, an external voltage is applied to drive the non-spontaneous reactions, which may exceed this value. The actual voltage required will depend on factors such as electrode surface area, temperature, and the specific setup of the cell.
