MUST ANSWER BOYH SUBPARTS A AND B A 1.161g sample of pure maleic acid (H2M, 116.1 g/mol) with Ka1 and Ka2 values of 1.42 × 10-2 and 8.57 ×10-7, respectively, was contained in a 100.0 mL solution with a pH of 5.0. In solution, maleic acid can dissociate into HM- and M2- species. The three species (H2M, HM- and M2-) exist in the solution at varying concentrations that depend on the pH of the solution. a) Calculate the values of α1 (alpha 1) and α3 (alpha 3). b) Calculate the concentration of HM- in the above solution.
