A 100.0 mL solution containing 0.8366 g of maleic acid (MW =
116.072 g/mol) is titrated with 0.3203 M KOH. Calculate the pH of
the solution after the addition of 45.00 mL of the KOH solution.
Maleic acid has pKa values of 1.92 and 6.27. 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 H2M,
HM–, and M2–, which represent the fully protonated, intermediate,...
