Use a spreadsheet to prepare a family of graphs for the titration of 50.0 mL of 0.020 M H2A with 0.100 M NaOH. Consider the following cases: (a) pK1 = 4.00, pK2 = 8.00; (b) pK1 = 4.00, pK2 = 6.00; (c) pK1 = 4.00, pK2 = 5.00.
You do this the same way you do the H2A problem you posted (pk1 = 4 and pk = 8). Then you graph the results. We can't draw graphs on this board.
