Name the product formed from the neutralization reaction of potassium hydroxide and hydrochloric acid.

When acid and base react together salt and water is formed and this reaction is known as neutralization. 

Potassium hydroxide (KOH) is a base and hydrochloric acid( HCl ) is an acid. So, when potassium hydroxide is mixed with hydrochloric acid, the product formed will be potassium chloride (salt) and water. 

The chemical equation is mentioned below:

$\mathrm{KOH}\left(aq\right)+ \mathrm{HCl}\left(aq\right) \to \mathrm{KCl}\left(aq\right) + {\mathrm{H}}_2\mathrm{O}\left(l\right)$
