When an acid and a base react, they undergo a neutralization reaction. This reaction results in the formation of:

* Salt: A compound formed by the cation from the base and the anion from the acid.

* Water: Formed from the hydrogen ion (H+) from the acid and the hydroxide ion (OH-) from the base.

Here's a simplified representation:

Acid + Base → Salt + Water

Example:

* Hydrochloric acid (HCl) + Sodium hydroxide (NaOH) → Sodium chloride (NaCl) + Water (H₂O)

Key points to remember:

* Acids release hydrogen ions (H+) in solution.

* Bases release hydroxide ions (OH-) in solution.

* Neutralization reactions are exothermic, meaning they release heat.

* The pH of the solution becomes closer to neutral (pH 7) after neutralization.
