31. There are most probably six water molecules in the primary solvation sphere of the sodium ion. 32. The final component of the total interaction energy is the solvation repulsion which is as follows: 33. Enthalpy of solvation can help explain why solvation occurs with some ionic lattices but not with others. 34. Enthalpy of solvation can help explain why solvation occurs with some ionic lattices but not with others. 35. The major challenge to the interpretation of such isotope affects is the solvation of the leaving group. 36. Thus, a separation based on a compound's polarity and degree of solvation takes place. 37. Under constant buffer conditions, thermophoresis probes the size, charge and solvation entropy of the molecules. 38. Solvation numbers less than 4 may be the result of the formation of contact ion-pairs.39. The acidities of phenol and acetone enol diverge in the gas phase owing to the effects of solvation . 40. :The challenge is providing an emulsion system for solvation of grease without dissolving or attacking your hands.
