NaCl is the molecular formula of sodium chloride, or common salt. It is an ionic compound with a three-dimensional lattice network of Na+ ions and Cl- ions. Ionic bonds are formed by the force of attraction between oppositely charged Na+ ions and Cl- ions.
The molecular mass of sodium chloride is 58.44 grams per mole. It is a white crystalline solid at room temperature with a melting point of 1,474 degrees Fahrenheit. The density of sodium chloride is 2.165 grams per centimeter cubed, and the compound's solubility in water is 359 grams per liter. An aqueous solution of sodium chloride is a good conductor of electricity. Sodium chloride is also referred to as table salt and is widely used in culinary preparations.
