The common name for a sodium chloride compound is table salt. Sodium chloride (NaCl) is an essential mineral that plays a crucial role in human health. It is primarily used in cooking to enhance the flavor of food, but it also serves important functions in preserving food and in various industrial processes. In the human body, sodium chloride helps regulate fluid balance, supports nerve function, and is vital for muscle contractions. While necessary in moderation, excessive consumption of table salt can lead to health issues such as hypertension and cardiovascular problems.
