The reaction between sodium oxide (Na2O) and water (H2O) produces sodium hydroxide (NaOH). This is a basic reaction where the oxide ion (O²⁻) from sodium oxide reacts with water to form hydroxide ions (OH⁻).
The balanced chemical equation for this reaction is:
\[ \text{Na}_2\text{O} + \text{H}_2\text{O} \rightarrow 2 \text{NaOH} \]
In this reaction, one mole of sodium oxide reacts with one mole of water to produce two moles of sodium hydroxide. Sodium hydroxide is a strong base and is commonly used in various industrial and laboratory applications.
