1Conductances at infinite dilution Λ0 are printed in italics without mentioning a concentration, units are Ω−1 mol−1cm2. Molar conductances are given in italics with a concentration value, units are Ω−1 mol−1cm2. Simple conductivities are given stating the concentration, units are Ω−1 cm−1

2Concentrations are molar (units: mol · dm−3), molal concentrations are given in italics (units: mol · kg−1), other concentrations as specified
