Which of the following acids produces more than one H₃O+ ion per molecule of acid when dissociated in water?

Question

Quizplus · Accepted Answer

Carbonic acid (H₂CO₃) produces two H₃O+ ions per molecule of acid when dissociated in water. The dissociation reaction is as follows: H₂CO₃ ⇌ H⁺ + HCO₃⁻  and HCO₃⁻ ⇌ H⁺ + CO₃²⁻. Both reactions release H⁺ ions, which combine with water molecules to form H₃O+ ions. The other acids in the list release only one H₃O+ ion per molecule of acid.
