Conductance... Case with three simple ionic species

At this approximaton order (first-order term and mean cut-off distance) the conductance is then given by [Pg.299]

This quantity is experimentally known with high precision. The closest-approach distance o is calculated hy fitting to the expression for the equivalent conductivity the conductance data of a given salt. The fitted o is, in all studied cases, slightly larger than the sum of the anion s and the cation s crystallographic radii a - At low concentrations 10 mol/L), theoretical results converge asymptotically to the ideal behaviour. [Pg.299]

Next figures give some examples for simple non-associated electrolytes. Concerning 2-1 salts, equivalent concentration and conductivity was chosen. [Pg.299]

Case with three simple ionic species [Pg.299]

Conductance of solutions containing more than two ion species was first theoretically studied in a systematic way by Onsager and Kim in 1957 [4]. [Pg.299]
