Hydrated Ion: Definition, Structure & Examples Study.com

WebThe role of hydrophobic hydration in the formation of biological membranes and in protein folding, as well as the importance of electrostatic interactions in the hydration of polar and ionic species, are all well known. However, the underlying molecular mechanisms of hydration are often not as well understood. Webthe free energy of ionic hydration depends on only two pa rameters, the ionic radius r and the relative dielectric con stant Er of the fluid. Quantitatively the Born model is rather inaccurate, the deficiencies being hard sphere assump tion for the ionic solute, and the treatment of the solvent as a continuous dielectric. delaware board of pharmacy self inspection
