An example of a chemical equation involving an acid is the reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH), which results in the formation of water (H₂O) and sodium chloride (NaCl), a salt. This type of reaction is known as an acid-base neutralization reaction.
The balanced chemical equation for this reaction is:
\[ \text{HCl} (aq) + \text{NaOH} (aq) \rightarrow \text{NaCl} (aq) + \text{H}_2\text{O} (l) \]
In this equation:
- \( \text{HCl} \) is the acid,
- \( \text{NaOH} \) is the base,
- \( \text{NaCl} \) is the salt produced, and
- \( \text{H}_2\text{O} \) is the water formed.
