solvation energy and solubility of ionic compounds???

The enthalpy change of arrangement is the enthalpy change when 1 mole of an ionic substance breaks up in water to give an answer of boundless weakening. Enthalpies of arrangement might be either sure or negative - at the end of the day, a few ionic substances broke up endothermically (for instance, NaCl); others disintegrate exothermically (for instance NaOH). Solvation portrays the cooperation of solventwith broke up particles. Ionized and uncharged particles, communicate emphatically with dissolvable, and the strength and nature of this collaboration impacts numerous properties of the solute, including dissolvability, reactivity, and variety, as well as affecting the properties of the dissolvable, for example, the thickness and density.In the course of solvation, particles are encircled by a concentric shell of dissolvable. Solvation is the method involved with rearranging dissolvable and solute atoms into solvation buildings. Solvation includes bond development, hydrogen holding, and van der Waals powers. Solvation of a solute by water is called hydration. The energy of solvation is how much energy related with dissolving a solute in a dissolvable. In the event that it is a positive number, the dissolving system is endothermic; assuming it is negative, it's exothermic
