Quick Summary

Salt is one of the five basic taste sensations, alongside sweet, sour, bitter, and umami. In chemistry, a salt is a substance formed from the reaction of an acid with a base, consisting of a positive ion from the base and a negative ion from the acid. Common table salt is sodium chloride (NaCl).1234

Saltiness is detected by taste buds, primarily located on the tongue, which contain receptor cells that respond to dissolved chemicals. While many water-soluble salts have a salty taste, some can also be bitter or sour, depending on their molecular weight and composition. The concentration of sodium ions is crucial for maintaining fluid and electrolyte balance within the body.51678
