A 100.0 mL solution containing 0.914g of maleic acid (MW=116.072 g/mol) is titrated with 0.281M KOH. Calculate the pH of the solution after the addition of 56.0 mL of the KOH solution. Maleic acid has pKa 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 M-, which represent the fully protonated, intermediate, and fully...
