21. This effect was extensively used in the 1950s and 1960s for characterizing ion solvation . 22. Hydration and solvation properties of Brodie and Hummers graphite oxides are also remarkably different. 23. The solvation number of mercury ( II ) is most likely to be 6. 24. :For the first question, see solvation . 25. Unfavorable interactions between proteins and osmolytes increases the solvation of the protein with water. 26. With aqua ions of high charge some information is obtained about the second solvation shell. 27. For potassium, rubidium and caesium even the primary solvation shell is not well defined. 28. Solvation involves the interactions between dissolved molecules ( solutes ) and molecules of the solvent.29. Thus, the needed atomic solvation parameters were initially derived from water-gas partition data. 30. This is referred to as solvation .
