salt - Science Definition
- Any of a large class of chemical compounds formed when a positively charged ion (a cation) bonds with a negatively charged ion (an anion), as when a halogen bonds with a metal. Salts are water soluble; when dissolved, the ions are freed from each other, and the electrical conductivity of the water is increased. See more at complex salt, double salt, simple salt.
- A colorless or white crystalline salt in which a sodium atom (the cation) is bonded to a chlorine atom (the anion). This salt is found naturally in all animal fluids, in seawater, and in underground deposits (when it is often called halite). It is used widely as a food seasoning and preservative. Also called common salt, sodium chloride, table salt. Chemical formula: NaCl.
