The Chemical Equations Below Show the Reaction of Al(OH)₃ as a Lewis

Short Answer

The chemical equations below show the reaction of Al(OH)₃ as a Lewis acid and as a Lewis base, respectively.
Al(OH)₃(s) + OH^-(aq) $\rightleftharpoons$ Al(OH)₄^-(aq)
Al(OH)₃(s) + 3 H₃O⁺(aq) $\rightleftharpoons$ Al³⁺(aq) + 3 H₂O( $\ell$ )
Substances that can behave as either Lewis acids or bases are called ________ substances.
