The graph below, which is related to a titration curve, shows the fraction (f) of the stoichiometric amount of acetic acid present as non-ionized CH3COOH and as acetate ion, CH3COO-, as a function of the pH of the solution containing these species. (Graph piture attached) Explain the significance of the point at which the two curves cross. What are the fractions and the pH at that point?
