Explanation:
Hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.
<h3>
Is Hydrochloric Acid considered a
Brønsted-Lowry acid?</h3>
Hydrochloric Acid HCl(g) is the proton donor and therefore a Brønsted-Lowry acid.
<h3>
Is Hydrochloric Acid considered an Arrhenius
acid?</h3>
According to Arrhenius theory, hydrochloric acid is an acid which gives hydrogen ions in water but according to Bronsted-Lowry theory, hydrochloric acid is an acid because it donates a proton to the water molecule.
<h3>Is
Hydrochloric Acid considered a Lewis acid?</h3>
Hydrochloric acid (HCl) cannot be classified as a Lewis acid since it cannot accept an electron pair.
Thus, hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.
