Classify the steps involved in the formation of a solution as being endothermic or exothermic. Endothermic a) Separation of solute molecules Ex: Interaction between ions of NaCl (10n - ions) b) Separation of solvent molecules Ex: Dipole - dipole attraction Exothermic a) formation of solute - solvent interactions Ex: Interaction between sodium ions and oxygen ions.
