Chemical nature, thermodynamic and kinetic properties of metal cations in aqueous solutions are de­scribed and discussed in terms of structural factors controlling physical properties of the systems. The structure of hydrated cations, reaction mechanism of water exchange on the cations, hydrolytic phenomena and acidity of the cations are presented. Correlations between coordination states of the salts in and bulk properties of the solutions are indicated. Elements of aquatic chemistry are presented.
