The chemical compound known as table salt is sodium chloride, often represented by the chemical formula NaCl. Sodium chloride is a crystalline solid that occurs naturally in seawater and is widely used in food preservation and flavoring. It is composed of sodium (Na) and chlorine (Cl) ions, which form an ionic bond. Beyond culinary uses, table salt has various industrial applications, including chemical manufacturing and de-icing roads during winter. While salt is essential for human health in moderation, excessive consumption can lead to health issues like high blood pressure. It is a staple in households worldwide.
