Which one of the following is an example of an acid-base reaction?

C. HCl + KOH → H₂O + KCl

Explanation:

An acid-base reaction or neutralization reaction is a chemical reaction that occurs between an acid and a base producing a salt and water.

According to Arrhenius, an acid is a substance that dissociates in aqueous solution forming hydrogen cations (H⁺), while the bases are those that dissociates to form hydroxyl anions (OH⁻).

On the other hand, a salt is an ionic compound whose cation comes from a base and whose anion comes from an acid.

As you can see, the only reaction of the options that meets the characteristics of an acid-base reaction is the reaction of option C. In this reaction an acid (hydrochloric acid HCl) reacts with a base (potassium hydroxide KOH) to produce water and a salt (potassium chloride KCl)
