Ethanol and sodium react to each other and produces a gas which burns in blue flame. Identify them and mention the reaction.

If a small piece of sodium is dropped into ethanol, it reacts steadily to give off bubbles of hydrogen gas and leaves a colourless solution of sodium ethoxide: CH3CH2ONa.

2CH3CH2OH + 2Na → 2CH3CH2O- + 2Na+ + H2(g)
