Sodium, being highly electropositive in character, reacts violently with water to produce an alkali and hydrogen gas. The reaction is highly exothermic in nature and the accumulated heat so produced ignites the hydrogen instantaneously giving off an explosion like impression. In fact, with relatively larger bead of sodium, an explosive reaction does take place. This is the reason it is advised not to pour water into vessels containing metallic sodium. Instead, the metal should be washed first with an orgnic solvent like ethanol or methanol and then water is to be employed. The reaction that takes place is: 2Na(s) + 2H2O -> 2NaOH(aq) + H2(g)
