Why is it necessary to take the acid-base properties of water into account when computing the hydronium ion concentration of very dilute solutions of strong acids ?
- The hydroxide ion produced from the dissociation of water reacts with most of the H+ ion produced from the acid.
- The dissociation constant for water is larger in dilute rather than in concentrated solutions of acids.
- The amount of H+ ion produced by the dissociation of water is significant compared to that produced by the acid.
- The conjugate base of the strong acid reacts with the hydroxide ion produced from the dissociation of water.
Answer
(C) The amount of H + ion produced by the dissociation of water is significant compared to that produced by the acid.
