Sodium chloride, an aa kent as saut, common saut, table saut or halite, is an ionic compound wi the formula NaCl, representin equal proportions o sodium an chlorine. Sodium chloride is the saut maist responsible for the salinity o the ocean an o the extracellular fluid of mony multicellular organisms. As the major ingredient in edible saut, it is commonly uised as a condiment an fuid preservative.
