Question

Sodium reacts rapidly with water to form sodium hydroxide solution and how is the gas released?

Answer 1

$2Na_{(s) }+ 2H_2O_{(l)} → 2NaOH_{(aq)} + H_{2(g)}$

Elementary sodium reacts strongly with water, according to the above reaction mechanism.

A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction. Sodium metal is heated and may ignite and burn with a characteristic orange flame. Hydrogen gas released during the burning process reacts strongly with oxygen in the air$.$
