Homework Help: Acid-Base low concentration of weak acid

  1. Dec 28, 2013 #1
    My textbook assumes that whenever K-constant of a weak acid is bigger than K-constant of water, the water should be a negligible source of H+ ions.

    However, how do we know that the concentration of weak acid could be too low and the H+ ions from water can actually have a significant effect?
