Ion dipole interaction energy
WebThe ion dipole interactions are always attractive resulting in a lowering of the potential energy. Since \(\mu\) is always positive, but q can be positive (cation) or negative … Webto overcome the desolvation energies of these ions, which are frequently very high. For example, the solvation energies of sulfate and potassium are esti-mated to be approximately 2300 and 280 kcal/mol, respectively.2–4 These solvation energies arise from the classic ion–dipole interaction between ions and water dipoles.
