검증된 단계별 안내1
Identify the definition of a strong acid: A strong acid is one that completely dissociates into its ions in an aqueous solution.
Consider the given compounds: Hydrochloric acid (HCl), Water (H2O), Acetic acid (CH3COOH), and Ammonia (NH3).
Evaluate Hydrochloric acid (HCl): It is known to completely dissociate into H⁺ and Cl⁻ ions in water, making it a strong acid.
Evaluate Acetic acid (CH3COOH): It is a weak acid because it only partially dissociates in water.
Evaluate Water (H2O) and Ammonia (NH3): Water is neutral and ammonia is a weak base, neither of which are strong acids.
