Abstract: In the light of the interactions between particles, this paper is a calculation of the standard solvation enthalpies for ions Li~+, Na~+, K~+, Rb~+, Cs~+, Ag~+, Cl~-, Br~- and I~- in solvents as H_2O, MeOH, FA, DMF, DMSO, MeCN, PC and SL. The contributions from the cavity formation process, electrostatic attraction, electrostatic repulsion and those from nonelectrostatic interactions are considered. The accordance between the calculated values and those from literature is good except Li~+.
