The ion transport number, also known as the transference number, is a measure of the contribution of a particular ion to the total electrical conductivity of an electrolyte solution. It quantifies the fraction of the total current conducted by a specific ion as it migrates in an electric field. In an electrochemical system, when an electric field is applied, ions in solution will move towards the electrodes.
