Precise electrical conductivities of dilute aqueous solutions of acetic acid and its lithium, sodium, potassium and cesium salts were determined from 278.15 K to 313.15 K. Conductivities of alkali metal acetates from the literature and measured here were discussed in the framework of dissociation and hydrolysis model. This was performed by using the Quint-Viallard conductivity equations for 1:1 type electrolytes and the Debye-Hückel expression for activity coefficients. Excellent agreement between experimental and calculated conductances permitted to evaluate over the investigated temperature range, a consistent and reliable set of the limiting conductances of acetate anion, their diffusion coefficients at infinite dilution and the Stokes radius. Without using additional parameters, the classical problem of representation of acetic acid conductivities in dilute solutions was reexamined and solved, indicating internal consistency of applied molecular models.
