ionic conductivity

Defined for ionic species B by

$λ = | z B | F u B$

where $z B$ is the charge number of the ionic species B, $F$ is the Faraday constant, and $u B$ is the electric mobility of species B. In most current practice $z B$ 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 $λ Ca 2+ / 2$ .
