The mineral commonly found in table salt is sodium chloride, often simply referred to as salt. Sodium chloride consists of sodium (Na) and chloride (Cl) ions, which are essential for numerous bodily functions, including nerve transmission and maintaining fluid balance. Table salt is often fortified with iodine to prevent iodine deficiency, which can lead to thyroid problems. Its primary use extends beyond seasoning food; it is also crucial in preserving food and various industrial processes.
