The chemical formula for table salt is NaCl, which stands for sodium chloride. It is composed of one sodium ion (Na⁺) and one chloride ion (Cl⁻), bonded together through ionic bonds. Sodium chloride is a simple compound that occurs naturally in seawater and is commonly used as a seasoning and preservative in food. The process of salt production often involves evaporating seawater or mining rock salt. Besides its culinary uses, NaCl is essential for human health, maintaining fluid balance, and regulating nerve and muscle function. It is also widely used in various industrial applications.
