When an acid reacts with a base, they undergo a neutralization reaction. This reaction produces:

* Salt: A compound formed from the positive ion of the base and the negative ion of the acid.

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

Here's a simplified breakdown:

Acid + Base → Salt + Water

Example:

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

Key things to remember:

* Acids donate hydrogen ions (H+).

* Bases accept hydrogen ions (H+).

* The reaction releases heat, making it an exothermic reaction.
