A 100.0 mL solution containing 0.923 g of maleic acid (MW = 116.072 g/mol) is titrated with 0.306 M KOH. Calculate the pH of the solution after the addition of 52.0 mL of the KOH solution. Maleic acid has pK₂ 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 H₂M, HM, and M2-, which represent the fully protonated, intermediate, and fully deprotonated forms, respectively. [M²-] = [HM¯] = [H₂M] = I M M M
