The reaction of hydrogen chloride (HCl) and sodium hydroxide (NaOH) produces sodium chloride (NaCl) and water (H2O). The chemical equation for this reaction is:

```

HCl + NaOH → NaCl + H2O

```

This reaction is a classic example of an acid-base reaction, where an acid (HCl) reacts with a base (NaOH) to form a salt (NaCl) and water. In this case, HCl is the acid and NaOH is the base. The products of the reaction are NaCl, which is a salt, and H2O, which is water.
