Defined for ionic species B by where is the is the is the 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 .
charge number
of the ionic species B, Faraday constant
, and electric mobility
of species B. In most current practice
