NaCl is the chemical name for table salt, which is approximately 40% sodium and 60% chloride. Salt is used as a condiment to flavor, season and preserve foods.
Common table salt, used in the replenishment of fluids and electrolytes and in irrigating mediums and enemas.
It is used in preparation of normal saline solution, as an emetic, and to add flavor to foods. It is incompatible with silver nitrate. In aqueous solution, sodium chloride, a neutral salt, is a strong electrolyte, being almost completely ionized. The sodium and chlorine ions are important in maintaining the proper electrolyte balance in body fluids. The kidneys regulate retention or excretion of sodium chloride in urine; aldosterone directly increases the renal reabsorption of sodium ions.
