Sodium was originally used in medieval times as a headache remedy. The mineral form halite, or rock salt, is sometimes called common salt to distinguish it from a class of chemical compounds called salts. Because of its importance in human health, salt has long been an important commodity, as shown by the English word salary, which derives from salarium, the wafers of salt sometimes given to Roman soldiers along with their other wages. There have been many cases of garbage trucks catching fire when the bulbs in the back broke. When sodium reacts with water it produces sodium hydroxide and hydrogen gas. Close. Davy isolated this sodium by means of electrolysis of caustic soda. Much later, in 1791 the Frenchman Nicolas Leblanc produced sodium carbonate or soda ash.
