Ionic mobility and transport number
In chemistry, ion transport number, also called the transference number, is the fraction of the total electric current carried in an electrolyte by a given ionic species i: $${\displaystyle t_{i}={\frac {I_{i}}{I_{\text{tot}}}}}$$Differences in transport number arise from differences in electrical mobility. For example, in … Meer weergeven There are several experimental techniques for the determination of transport numbers.
