3) Consider the titration of 40.0 mL of 0.100 M maleic acid (HzM) with 0.200 M NaOH. Maleic acid is diprotic with Kal 1.20 x 102 and Ka2 = 5.96 x 107. At volumes in the titration that are between the first and second equivalence points, the solution can best be described as containing a) a buffer of H2M and HM. b) a buffer of HM and M2. c) HM. d) M. c) M and excess NaOH. b. Consider the titration of 40.0 mL of 0.100 M maleic acid (H2M) with 0.200 M NaOH. Maleic acid is diprotic with Kal 1.20 x 102 and Ka2 5.96 x 107, When 12.0 mL of the NaOH solution has been added, what of the concentration of H2M that is plugged into the appropriate K. expression in order to calçulate [H3O'] ? a) 0.0320 M b) 0.100 M c) 0.128 M d) 0.0480 M e) 0.0400 M %!
