Abstract: An empirical formulation modifying the Nernst equation to incorporate the selectivity factor, β, is tested with eighteen systems taken from literature to assess its reliability in correlating the LLE data. This simple equation relates the selectivity factor to the ratio of the mass of the solvent to that of the diluents in the solvent phase. The correlation coefficient is almost unity for all the systems. The value of the intercept, In(A), in the modified Nernst equation, In(β)= B In (XBB/XAB)+ In (A) is found to be in direct proportion with solvent selectivity. The equation is also found effective in predicting the salt effect in salt containing ternary liquid systems.
