The main mineral found in table salt is sodium chloride, commonly known as salt. Sodium chloride is composed of sodium (Na) and chlorine (Cl) elements, creating a crystalline structure that is highly soluble in water. This mineral is essential for various bodily functions, including regulating fluid balance, nerve transmission, and muscle function. In addition to its culinary uses, table salt often contains additives like iodine, which helps prevent iodine deficiency in populations. Salt has been a crucial part of human history and economy, used not only for flavoring and preservation of food but also for various industrial applications.
