Question #14e86

1 Answer

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)"#
