Question

Explain Hydration of ions.

Answer 1

Enthalpy of hydration, Hhyd, of an ionis the amount of energy released when a mole of the ion dissolves in a large amount of water forming an infinite dilute solution in the process, Mz+(g) + mH2O ® Mz+(aq) where Mz+(aq) represents ions surrounded by water molecules and dispersed in the solution.
