Web4 mei 2024 · As mentioned above, ionic conductivity is the most desired property of an electrolyte for many applications. The charge carrier density and mobility govern the conductivity of an electrolyte, and thus, the determination of these charge transport parameters is critical to characterize an electrolyte. For a single-ion conductor Eq. 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.
