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 in numerous industrial applications like:-
Strong base sodium hydroxide and the strong acid hydrochloric acid when neutralized, it produces the Sodium Chloride. It is also obtained by mining the rock salt. It is so easily obtained by mineral halite.
