As sodium metal is added to water, it rapidly reacts with the water molecules, transferring electrons from sodium atoms to oxygen atoms in the water molecules. This transfer of electrons causes the sodium atoms to become positively charged ions (Na+) while the oxygen atoms gain negative charge and form hydroxide ions (OH-).
The chemical equation for this reaction is:
2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
The reaction between sodium and water is incredibly vigorous, and it produces a large amount of heat and hydrogen gas. The heat generated during the reaction can cause the water to boil and splatter, while the hydrogen gas produced is flammable and can ignite spontaneously in air.
It is essential to note that this reaction should be carried out with extreme caution and appropriate safety measures, as it can be potentially hazardous due to the risk of fire and caustic properties of sodium hydroxide.
