Sodium Reacting with Water

2Na + 2H₂O → 2NaOH + H₂

Tổng quan

Sodium metal reacts violently with water to produce sodium hydroxide and hydrogen gas. The reaction is so exothermic that the hydrogen often ignites, burning with a yellow flame from sodium vapor. The sodium dashes across the water surface as a molten ball due to the heat generated.
