You have been given the task to analyze a large number of samples that contain an unknown concentration of the diprotic acid, oxalic acid. You know the concentration is approximately 0.005 to 0.015 M H2C2O4 . However, you do not want to complete a myriad of pH titrations, so you decide to identify some of the expected pH values you will encounter. In order to do so, you have prepared 50.00 mL of 0.0110 M H2C2O4 solution as your test solution. You will be titrating the H2C2O4 solutions with 0.0160 M NaOH. Based on this information: (1) Calculate the pH of the titration solution once the first equivalence point has been reached. (2) Calculate the pH of the titration solution once the second equivalence point has been reached. (3) Calculate the pH of the titration solution once 150.0 mL of the NaOH has been added.
