WebHydration enthalpy is the quantity of energy produced when 1 mole of the gaseous ions is mixed with H 2 O (water) to produce hydrated ions. The various factors that determine the hydration enthalpy are Ionic Radius and Ionic Charging. The chemical reactions that produce the heat in water and cement work on the principle of Hydration Enthalpy. WebWhat does hydration enthalpy depend on? Factors Affecting the Size of Hydration Enthalpy. With negative ions, ion-dipole attractions are formed between the negative ions and the δ + hydrogens in water molecules. The size of the hydration enthalpy is usually governed by the amount of attraction between the ions and the water molecules.
