Sodium chloride facts

  • Sodium chloride is a white ionic solid that forms cube-shaped crystals and is best known as table salt.
  • It is mined from underground rock salt deposits or made by evaporating seawater, and it is used to season and preserve food and to de-ice roads.
  • Solid salt does not conduct electricity, but melted salt or salt dissolved in water does because its sodium and chloride ions are free to move.
