The salt that forms from the reaction between hydrochloric acid (HCl) and calcium hydroxide (Ca(OH)₂) is calcium chloride (CaCl₂) .

Here's the balanced chemical equation for the reaction:

2HCl(aq) + Ca(OH)₂(aq) → CaCl₂(aq) + 2H₂O(l)

Explanation:

* Acid-Base Reaction: This is a classic acid-base neutralization reaction. The hydrochloric acid (HCl) is a strong acid, and calcium hydroxide (Ca(OH)₂) is a strong base.

* Neutralization: The hydrogen ions (H⁺) from the acid react with the hydroxide ions (OH⁻) from the base to form water (H₂O).

* Salt Formation: The remaining ions, calcium (Ca²⁺) and chloride (Cl⁻), combine to form the salt calcium chloride (CaCl₂).
