used in electrolysis of an aqueous solution is analogous to the process used in electrolysis of water. Yet, it is thought
to be a more complex process because the contents of the solution must be analyzed in half reactions, whether reduced or oxidized.
In the electrolysis of aqueous solutions only
one ion is implicated in the selective discharge of ions at each electrode during electrolysis. The ion selected for discharge
at an electrode relies upon a number of factors, including position of the ions in the electrochemical series, concentration
of ions in the solution, and the nature of the electrode.
