The molar conductivity of an electrolyte solution is defined as its conductivity divided by its molar concentration.[1][2]
where:
- κ is the measured conductivity (formerly known as specific conductance),[3]
- c is the molar concentration of the electrolyte.
The SI unit of molar conductivity is siemens metres squared per mole (S m2 mol−1).[2] However, values are often quoted in S cm2 mol−1.[4] In these last units, the value of Λm may be understood as the conductance of a volume of solution between parallel plate electrodes one centimeter apart and of sufficient area so that the solution contains exactly one mole of electrolyte.[5]
