Chapter 17, Problem 92(choose chapter or problem)
The graph below, which is related to a titration curve, shows the fraction of the stoichiometric amount of acetic acid present as non-ionized and as acetate ion, as a function of the pH of the solution containing these species. (a) Explain the significance of the point at which the two curves cross. What are the fractions and the pH at that point? (b) Sketch a comparable set of curves for carbonic acid, [Hint: How many carbonate-containing species should appear in the graph? How many points of intersection should there be? at what pH values?] (c) Sketch a comparable set of curves for phosphoric acid, [Hint: How many phosphate-containing species should appear in the graph? How many points of intersection should there be? at what pH values?]
