Abstract
Activity coefficients and thermodynamic association constants have bee n estimated for NaBr, NaCl, NaI, NaClO4, Bu4NBr, Bu4NI, and Bu4NClO4 e lectrolytes in methanol by means of a fit of experimental data to theo ry using the unrestricted version of the mean spherical approximation. Realistic sizes for the solvated ions and for ion pairs have been det ermined. The thermodynamic association constants derived are compared with values obtained from conductance studies.
