hydration enthalpy
Asked by ankit malhotra | 9th Nov, 2013, 12:49: PM
Expert Answer:
- This is the energy change when 1 mole of a gaseous species dissolves in an infinite volume of water.
- It is caused by the solvent water molecules bonding to the dissolving species.
- It is always an exothermic process as bonds are being formed.
Example: The hydration enthalpy of the sodium ion
Na+(g) + (aq) Na+(aq) ?H = -405 kJ mol-1
