Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Question

A concentration cell is one wherein the concentrations of the same ion in the two electrodes are
different. Due to this difference, a potential is measured but there is no redox reaction taking
place. Consider the following data for a concentration cell consisting of copper ions. The cell
notation is given as
Cu| Cu2+ (x M) || Cu2+ (y M) | Cu
Verify the accuracy of the cell potentials measured at 27.5°C shown in the table below for a
copper concentration cell using the Nernst Equation. Show your complete solution to justify your
conclusion.
