Enter a chemical equation for HI(aq) showing how it is an acid or a base according to the Arrhenius definition. Consider that st
jek_recluse [69]

Answer:

HI (aq) → H⁺ (aq) +  I⁻ (aq)

HI (aq) +  H₂O(l)  → H₃O⁺ (aq) +  I⁻ (aq)

Explanation:

The Arrhenius acid concept indicates that a substance behaves like acid if it produces hydrogen ions H⁺ or hydronium ions H₃O⁺ in water. A substance will be classified as a base if it produces OH⁻  hydroxide ions in water. This way of defining acids and bases works well for aqueous solutions.

When we mix HI (aq) and water, we are increasing [H₃O⁺]

HI (aq) → H⁺ (aq) +  I⁻ (aq)

HI (aq) +  H₂O(l)  → H₃O⁺ (aq) +  I⁻ (aq)
