  • The sign convention regarding current is such that the migration current is positive for the oxida- tion of a cation or the reduction of an anion and is negative for the reduction of a cation or for the oxidation of an anion. Hence, the migration current may either increase or decrease the total current observed. The migration current approaches zero as the transport number of the electroactive sub- stance is decreased by increasing the concentration of supporting electrolyte, and hence the conduc- tivity of the solution.
