The Gibbs\u27 free energies of transfer of silver(I) ion, AtG° (Ag+), from water to water-dimethyl sulfoxide (W/D) binary mixtures have been used to obtain the distribution of solvated ions, [AgW/Dfc]+, present over the mole fraction range from 0.05 to 0.95 for dimethyl sulfoxide. Major species were [AgWsD]+, [AgW1gD]+, [AgW3D2]+, [AgWD3]+, [AgDg]+, [AgWD9]+, [AgD14]+. The water-rich solvated ions were present only at small dimethyl sulfoxide concentrations
