검증된 단계별 안내1
Identify the nature of each compound listed: Ammonia (NH3) is a weak base, Acetic acid (CH3COOH) is a weak acid, Hydrochloric acid (HCl) is a strong acid, and Water (H2O) is neutral.
Understand the concept of acid strength: A strong acid is one that completely dissociates in water, releasing a high concentration of hydrogen ions (H+).
Compare the dissociation of each compound in water: NH3 does not dissociate to release H+ ions, CH3COOH partially dissociates, HCl completely dissociates, and H2O is neutral and does not contribute significant H+ ions.
Recognize that Hydrochloric acid (HCl) is known for its complete dissociation in aqueous solution, making it a strong acid.
Conclude that among the given options, Hydrochloric acid (HCl) is the compound considered a strong acid in aqueous solution due to its complete ionization.
