The balanced reaction of ethyl acetate (CH₃COOCH₂CH₃) and NaOH is a hydrolysis reaction where the ester bond is broken down by the hydroxide ions (OH-) from NaOH.

Here's the balanced equation:

CH₃COOCH₂CH₃ + NaOH → CH₃COONa + CH₃CH₂OH

Explanation:

* Ethyl acetate (CH₃COOCH₂CH₃) is the ester.

* Sodium hydroxide (NaOH) is the base that provides the hydroxide ions.

* Sodium acetate (CH₃COONa) is the salt formed from the reaction.

* Ethanol (CH₃CH₂OH) is the alcohol produced.

Mechanism:

1. The hydroxide ion (OH-) from NaOH attacks the carbonyl carbon of ethyl acetate.

2. This attack breaks the ester bond and forms a tetrahedral intermediate.

3. The tetrahedral intermediate collapses, releasing ethanol and forming acetate ion (CH₃COO-).

4. The acetate ion reacts with sodium ion (Na+) to form sodium acetate (CH₃COONa).

This reaction is commonly used in the production of soap and other chemicals.
