When an acid reacts with a base, the reaction is called neutralization, and the primary compounds formed are salt and water.

Here's a breakdown:

* Acid: A substance that donates hydrogen ions (H+) in solution.

* Base: A substance that accepts hydrogen ions (H+) in solution.

The reaction:

Acid + Base → Salt + Water

Example:

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

Explanation:

* The hydrogen ions from the acid combine with the hydroxide ions (OH-) from the base to form water (H₂O).

* The remaining ions from the acid and base combine to form a salt.

Note:

* The salt formed may be soluble or insoluble in water, depending on the specific acid and base involved.

* The reaction is usually exothermic, meaning it releases heat.

* The pH of the solution will become closer to neutral (around 7) as the acid and base neutralize each other.
