A 100.0 mL solution containing 0.918 g of maleic acid (MW = 116.072 g/mol) is titrated with Ö.298 M RÖH. Calculate the pH of the solution after the addition of 53.0 ml. of the KOH solution. Maleic acid has pK, values of 1.92 and 6.27. pH = At this pH, calculate the concentration of each form of maleic acid in the solution at equilibrium. The three forms of maleic acid are abbreviated as H,M, HM¯ , and M²-, which represent the fully protonated, intermediate, and fully deprotonated forms, respectively. (M²-] = | [HM) = (H,M] =
