Aluminum Hydroxide as Amphoteric Base with HCl
Al(OH)3 + 3HCl → AlCl3 + 3H2O
概述
Aluminum hydroxide dissolves in hydrochloric acid, demonstrating its basic character. As an amphoteric substance, Al(OH)₃ can act as either an acid or a base. With HCl, it donates its hydroxide ions to neutralize the acid. The gelatinous white precipitate dissolves to form a clear solution.
