Sodium Chloride (NaCl): Properties, Uses, and Importance
Sodium Chloride (NaCl): Properties, Uses, and Importance Introduction Sodium chloride (NaCl), commonly known as salt, is a vital compound in both nature and human life. It is composed of sodium (Na) and chloride (Cl) ions and is widely used in food, industry, and medicine. Found naturally in seawater and mineral deposits, NaCl plays a crucial role in various biological and chemical processes. Chemical and Physical Properties Sodium chloride is a white, crystalline solid with a cubic structure. It has a molecular weight of 58.44 g/mol and a melting point of 801°C. It is highly soluble in water and dissociates into sodium (Na⁺) and chloride (Cl⁻) ions, making it essential for maintaining electrolyte balance in the human body. Natural Sources NaCl is abundant in nature, primarily found in: Seawater : The oceans contain vast amounts of dissolved sodium chloride. Rock Salt (Halite) : Mined from salt deposits formed by evaporated ancient seas. Brine : Saltwater sources such a...
