The salt that is formed during the reaction between potassium hydroxide and hydrochloric acid is

Sodium chloride (NaCl)

Explanation:

According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.

Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.

For example: Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)

A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).

The chemical equation for this Neutralization reaction:

HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)

Therefore, sodium chloride (NaCl) is the salt formed during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).
