What are the inorganic and organic salts

The term usually used colloquially for sodium chloride (table salt, rock salt), is used in chemical jargon to describe compounds made up of cations and anions that crystallize in regular, highly symmetrical lattice structures (ion or crystal lattices). The cohesion of the ions in a salt is brought about by the ionic bond, i.e. by Coulomb forces between anions and cations.

Crystalline salt structures are often characterized by a particular stability due to the sometimes considerable lattice energies released during their formation, resulting in high melting and boiling points. When a salt dissolves in a polar solvent such as water, the lattice building blocks are solvated (in water: hydration). With numerous salts, however, the energy required to break down the lattice (it corresponds to the amount of the lattice energy) cannot be compensated for by the released solvation or hydration energy, even at higher temperatures; these compounds are sparingly soluble in water or other solvents.

Salt solutions and melts usually show good electrical conductivity. Organic salts are compounds in which at least one anion or cation comes from the field of organic chemistry, e.g. acetates, citrates.
