Abstract Values ofI ij calculated from experimental data are given for AgNO3 at 25°C. Experimental values of the ratioI 12/I21 are calculated to provide a sensitive direct test of the Onsager reciprocal relations,I 12=I21. This ratio is found to be unity within experimental error (ca. 2%). The general physical interpretation ofI ij/N as mobilities is discussed. An approximate way of estimatingI ij for dissociated salts is considered. A comparison is made between AgNO3 I ij data and corresponding data for NaCl and KCl. It is concluded that ion-pair formation (1) sharply increases the magnitude of the interaction mobility,I 12/N; and (2) increases the “intrinsic mobility” of Ag+,I 11/N, and decreases the intrinsic mobility of NO 3 − ,I 22/N.
