Salts are chemical compounds that are composed of positively and negatively charged ions (cations or anions). The chemical compound that exists between such ions is called ionic bond. Cations are often formed of metals in inorganic salts. The anions mostly come from non-metals or their oxides. Anions and cations form an ionic lattice together in a solid. If at least one anion or cation originates from an organic compound, this is called an organic salt.
