Write a balance equation for the reaction of NaOH and ethanoic (acetic) acid.

CH3COOH + NaOH → CH3COONa + H2O

The balanced equation for the reaction between sodium hydroxide (NaOH) and ethanoic (acetic) acid (CH3COOH) can be written as:

CH3COOH + NaOH → CH3COONa + H2O

In this reaction, acetic acid reacts with sodium hydroxide to form sodium acetate and water.
