Conductance measurements for fifteen uni-univalent salts in 2-methylpyridine-N -oxide (2-MPO) were made over the concentration range of 2-120 X 10 /sup -4/ mol-dm /sup -3/ at 55/sup 0/C. All conductance data were evaluated by the Lee-Wheaton equation. The results indicate that all of the salts studied are slightly associated in 2-MPO, which is, nevertheless, a reasonably good ionizing solvent compared to other solvents having a similar value for the dielectric constant. The tetraalkylammonium halides are weaker electrolytes than the tetraphenylborate salts in 2-MPO. Ionic limiting molar conductances were obtained by using as a reference electrolyte tris(iso-pentyl)butylammonium tetraphenylborate. Anions appear to be poorly solvated in this solvent but certain cations, particularly Na/sup +/ and K/sup +/, show evidence of specific ion-solvent interaction.
