Questiоn 9 (20 pоints) There аre twо pаrts to this question (а and b). Points: a = 8, b = 12, total = 20 points. A 50.00 mL aliquot of 0.100 M maleic acid (HO2C(CH)2CO2H) is titrated with 0.100 M NaOH. Ka1 = 1.20 × 10−2 and Ka2 = 5.37 × 10−7 for maleic acid. Part a). Sketch a titration curve for this titration.Part b). Calculate the pH after 70.00 mL of 0.100 M NaOH has been added.
