Summary Enthalpies of solvation of alkali halides in formamide, N-methylformamide, N-methylacetamide, N,N-dimethylformamide, water, methanol and ammonia have been divided into the contributions of the separate ions by means of two splitting procedures. The first one is based on the continuum model, the second on a discontinuous model of ionic solvation. Resulting values of the enthalpies of solvation of alkali and halide ions in the different solvents show that the splitting procedure according to the discontinuous approach is superior.
