Inorganic Salts are the compounds formed when an inorganic base reacts with an inorganic acid. Under these circumstances, the base provides the cation while the anion is derived from the acid. In the naming of Inorganic Salts, the name of the cation (or cations) normally precedes the name of the anion (e.g., Sodium Sulfate or Aluminum Zirconium Octachlorohydrate). Salts as a rule are ionized and, in the case of water-soluble salts, cations and anions are present as individual species although electroneutrality must be maintained. Thus an aqueous solution of silver nitrate contains silver cations and nitrate anions in stoichiometrically equivalent amounts. Solubility in water is not a criterion for ionization since solids (e.g., Sodium Chloride) have been shown to be ionized in their crystalline forms.
In cosmetics, salts are used for diverse purposes, which include thickening of shampoos, buffering, antiperspirants, oral care agents, and oxidizing or reducing agents. |
