HClO(aq) + H2O(l) ⇄ H3O+(aq) + ClO−(aq) The reaction between hypochlorous acid and water is represen — Acids and Bases Chemistry Question

HClO and ClO− OR H₂O and H₃O⁺

1 point is earned for a correct answer.

See dashed curve above. The curve starts below the HClO curve, rises slowly from 0 to 20 mL, then steeply reaches equivalence at pH 7 and 25 mL of NaOH added.

1 point is earned for a curve that has the shape of a titration curve, that starts at a pH below the first curve, and that ends above pH 7.
1 point is earned for a curve that shows an equivalence point at 25 mL.

A buffer solution contains a large concentration of both members in a weak acid/weak base conjugate pair. This solution would not be a buffer because HClO₄ is a strong acid, therefore ClO4− is negligibly basic and cannot react with added H₃O⁺.

1 point is earned for a valid explanation.
