Explanation:
It is odorless, white, cubic crystals with salty taste. Salt is hygroscopic in nature. Due to strong electrostatic force of attraction between ions, the melting point of sodium chloride is 800.8 °C and boiling point is 1465 °C. Its vapour pressure at 865 °C is 1 mm Hg and density of NaCl is 2.165gcm3.
