A 100.0 ml. solution containing 0.794 g of maleic acid (MW = 116.072 g/mol) is titrated with 0.228 M KOH. Calculate the pH of the solution after the addition of 60.0 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 M?-, which represent the fully protonated, intermediate, and fully deprotonated forms, respectively. [M-]3= (HM"| =
