Abstract

 

The Gibbs free energies, enthalpies for the solution of some ions were gathered from literature values and from them the transfer solution energies from water to the organic solvent were calculated. Also the entropies of transfer ions , Li + , Na + , K + , Rb + , Cs + , Cl - , Br -,  and iodide were calculated for transfer from water to the organic solvents at 298.15 K.
