## ionic conductivity

https://doi.org/10.1351/goldbook.I03175
Defined for ionic species B by $$\lambda = |z_{\text{B}}|\ F\ u_{\text{B}}$$ where $$z_{\text{B}}$$ is the @C00993@ of the ionic species B, $$F$$ is the @F02325@, and $$u_{\text{B}}$$ is the @E01932@ of species B. In most current practice $$z_{\text{B}}$$ is taken as unity, i.e. ionic conductivity is taken as that of species such as Na+, Ca2+/2, La3+/3 etc. To avoid ambiguity the species considered should be clearly stated, e.g. as $$\lambda (\text{Ca}^{\text{2+}}/2)$$.
