Calculate the molar concentrations of oxalic acid (COOH)2, HOOCCO2-, (CO2)22-, H3O+, and OH- in 0.15 M (COOH)2 (aq). This is a special case of general diprotic acid dissociation. First, we need to find the pKa1 and pKa2 in the water at room temperature, which is available in the textbook page 192 table 8.2. It is also available online e.g. Wikipedia (oxalic acid). pKa1 = 1.23, pKa2 = 4.19. Either solve numerically or analytically. Report here [H3O+] = ______ M. 2 sig. figures.
