Answer:
When one mole of gaseous hydrogen ions (H⁺) are dissolved in water to form infinitely dilute solution, the amount of heat is released is called hydration enthalpy.
Explanation:
- When one mole of an ionic substance dissolves in water to form a solution of infinite dilution cause the change in enthalpy of solution.
- Enthalpies of solution can be either positive (+ve) or negative (-ve). When one mole of NaCl crystals are dissolved in water, the enthalpy change of solution is equal to +3.9 kJ/mol.
- Some ionic substances dissolve endothermically such as NaCl and others dissolve exothermically such as NaOH.
- Hydration enthalpy determines the energy liberated due to the attractions between positive or negative ions and water molecules.
- Hydration enthalpy depends upon the amount of attraction between the ions and the water molecules. The smaller the ion more stronger attractions. If highly charged the ion then the attractions are more stronger.
