The quivalent conductances of KCl, KBr, and KI were measured in n-PrOH-Water mixtures at 25℃. The conductances of these electrolytes increase with the crystalgraphic radii of anions, which are expected from electrotatistical explanation. The concentration effect on the conductance appears to change with the change of composition of the alcohol in solvent mixtures. The association constant K, the ion-size parameter a, and the limitting equivalent conductanc ∧。 were calculated by using the conductance equations. The result have been discussed comparing with the data in water, methanol-water, and ethanolwater. a and K show the tendency to increase with the size of alcohols in solvent mixtures. The ion-size parameter(solvation radii) r_h were also calculated by Walden's rule. This gives considerable lower value than a.
