You have prepared a solution by dissolving 0.20 mol glutaric acid (C5H8O2, pKa1 = 4.34, pKa2 = 5.42) and 0.10 mol mandelic acid (C8H8O3, pKa = 3.86) in 1.00 L of water. Write all equilibria occurring in solution as well as mass balance and charge balance expressions for this system. Determine the pH of this solution. I was suggested to use a spreadsheet. I can work the spreadsheet, but I can't get to equations that describe the whole system.
