What is the balanced chemical equation for the reaction between aspirin and sodium hydroxide?

The balanced chemical equation for the reaction between aspirin (acetylsalicylic acid) and sodium hydroxide is:

[ \text{C}_9\text{H}_8\text{O}_4 + \text{NaOH} \rightarrow \text{C}_9\text{H}_7\text{O}_4\text{Na} + \text{H}_2\text{O} ]

In this reaction, acetylsalicylic acid reacts with sodium hydroxide to form sodium acetylsalicylate and water.
