Sodium Chloride (NaCl) is an inorganic chemical compound commonly referred to as an edible form of table salt. It is an ionic compound. It has a substantial chemical and industrial role. It is a common salt, found in seawater in a huge amount. It is a salt of a halogen and alkali metal. It is freely soluble in water. The salt solution of Sodium Chloride is called brine. It is an inorganic chloride and a metal halide.
Its appearance is a white and crystalline powder. It is a face-centered cubic structure. It is soluble in ethanol and water. On decomposing, it emits toxic fumes of hydrochloric acid. It has a salty taste. It is stable in storage condition. It has a 1:1 ratio of chloride and sodium ions. It has neither acidic nor basic properties.
- It is used as an electrolyte due to sodium ion.
