PHYSICAL PROPERTIES
- Odourless, white, cubic crystals
- Hygroscopic
- Characteristic salty taste
- Melting point = 800.8 °C
- Boiling point = 1465 °C
- Density = 2.165 g/cm³
- Solubility at 25 °C = 35.9 g/100 g water
- Vapour pressure at 865 °C = 1 mm Hg
- Solid does not conduct electricity
- Liquid conducts electricity
- Aqueous solution conducts electricity
CHEMICAL PROPERTIES
- Does not undergo combustion
- Electrolysis of molten NaCl forms chlorine gas and metallic sodium
#"2NaCl(l)" → "2Na(l)" + "Cl"_2"(g)"#
- Concentrated sulfuric acid converts it to hydrogen chloride
#"2NaCl(s)" + "H"_2"SO"_4"(l)" → "Na"_2"SO"_4(s) + 2"HCl"(g)#
- Aqueous solution reacts with aqueous silver nitrate to form silver chloride
#"NaCl(aq)" + "AgNO"_3"(aq)" → "NaNO"_3"(aq)"+ "AgCl(s)"#
