1. Acid-base neutralization reaction:
Naproxen Sodium is a salt compound consisting of two parts: Naproxen molecule and sodium ion (Na+). In a typical acid-base neutralization reaction, sodium ions react with the carboxyl group (-COOH) in the Naproxen molecule to form salts.

The chemical formula of Naproxen molecule is: C14H14O3
The chemical formula for sodium ion is: Na+
When these two compounds come into contact and mix, an acid-base neutralization reaction occurs, producing Naproxen Sodium.
The chemical formula of Naproxen Sodium is:
C14H14O3 + Na+ → C14H13NaO3
A chemical equation represents the chemical changes that occur in an acid-base neutralization reaction. In this equation, a hydrogen ion (H+) in the carboxyl group in the Naproxen molecule combines with a sodium ion (Na+) to generate Naproxen Sodium.
