What Happens When Na2O Reacts With Acid Or Water?

When Na2O reacts with water, it forms sodium hydroxide (NaOH) according to the following reaction: Na2O + H2O → 2NaOH. This reaction is highly exothermic, releasing a large amount of heat.

When Na2O reacts with an acid, such as hydrochloric acid (HCl), it undergoes a neutralization reaction to form sodium chloride (NaCl) and water (H2O): Na2O + 2HCl → 2NaCl + H2O. The reaction between Na2O and an acid is also highly exothermic.

Overall, the reaction of Na2O with water or an acid produces a strong base (NaOH) or a salt (NaCl), respectively.
