Which element will be oxidized and which will be reduced
The reduction potentials of two elements indicate their tendency to gain or lose electrons during a redox reaction. A higher reduction potential signifies a greater likelihood of gaining electrons and being reduced, while a lower reduction potential indicates a greater tendency to lose electrons and be oxidized. By comparing the reduction potentials, one can predict the direction of the electron flow in the reaction, determining which element will act as the oxidizing agent and which will act as the reducing agent. This information helps in assessing the feasibility and spontaneity of the redox reaction.
The element with the greater reduction potential is the one that is reduced.

The voltage of a galvanic cell made with silver and nickel will depend on the specific half-reactions involved. However, using standard reduction potentials, the cell voltage can be calculated as the difference between the reduction potentials of the two metals.
-3.27V
The total reduction potential of the cell can be calculated by finding the difference between the reduction potentials of the two half-reactions at standard conditions. The reduction potential for K reduction is -2.92 V and for Cu oxidation is 0.34 V. So, the total reduction potential for the cell would be (-2.92 V) - 0.34 V = -3.26 V.
The overall voltage for the non-spontaneous redox reaction between Mg and Cu can be calculated by finding the difference in standard reduction potentials between the two half-reactions. The standard reduction potentials for Mg and Cu are -2.37 V and 0.34 V, respectively. Therefore, the overall voltage would be (-2.37 V) - (0.34 V) = -2.71 V.
