The balanced chemical equation for the reaction between NaOH (sodium hydroxide) and CH₃COOH (acetic acid) is:

NaOH(aq) + CH₃COOH(aq) → CH₃COONa(aq) + H₂O(l)

Here's a breakdown:

* NaOH(aq): Sodium hydroxide dissolved in water (aqueous solution).

* CH₃COOH(aq): Acetic acid dissolved in water (aqueous solution).

* CH₃COONa(aq): Sodium acetate dissolved in water (aqueous solution).

* H₂O(l): Liquid water.

This reaction is a neutralization reaction where an acid (CH₃COOH) reacts with a base (NaOH) to produce a salt (CH₃COONa) and water (H₂O).
