IF we have the solubility value of a covalent compound that is non-polar, in various solvents like water, acetonitrile, dioxane etc., how to obatin the corresponding solvation energies?
Please respond to me at skumarami@yahoo.co.in
Can anyone provide a reference that says "dipole-dipole attraction is approximately 1/100 hydrogen bonding, and London Force is approximately 1/100 dipole-dipole interactions"? I do not think this is right, especially for liquids. To the contrary, it is often claimed in textbooks that almost all enegy of H-bonds is acually dipole-dipole interaction, especially when the molecules are highly mobile as in liquids. Obviously, the dipole-dipole attractions in nonpolar solvents will be close to zero, so that London force can be predominant.Biophys 05:45, 6 November 2006 (UTC)
[edit] solvation & hydration
what is the difference between solvation enthalpy and hydration enthalpy?What actually happens on adding a solute to a solvent in terms of the above said enthalpies? ANY ANSWERS,KINDLY MAIL ME AT aratinair@hathway.comAarti nair 15:28, 9 December 2006 (UTC)
I believe that the difference is just specificity. Hydration refers to water, but solvation doesn't have to. The enthalphy has to do with whether the solvent and solute are attracted to each other or not. Things that are getting more stable are also getting to a point of lower energy. Lower energy = more stable. Next time try Yahoo! Answers if you want a more immediate response. Good question, though. If anyone else can add more information, please jump in. --TLG 07:18, 12 December 2006 (UTC)

[edit] enthalpy of solvation
The statement that the enthalpy of solvation of gases is postive, making them less soluble at high temp, seems odd. If a reaction is endothermic, an increase in temp would favor the products, or dissolved phase, but that is opposite of the Wikipedia statement. —The preceding unsigned comment was added by 69.109.231.83 (talk) 08:12, 2 March 2007 (UTC).
