Sodium was first isolated by Sir Humphry Davy in the year 1807. An electric current was passed through molten sodium hydroxide to separate sodium.
The chemical characteristics of sodium are:
- Reacts exothermically with water.
- Forms sodium peroxide when burned in air.
- Sodium compounds are soluble except for feldspars compounds.
The physical characteristics are:
- Soft metal at room temperature.
- When exposed to air the bright silver luster of sodium rapidly tarnishes.
- Highly reactive
-
