A. You have 150 ml of a solution of pure oxalic acid with an unknown concentration.  You add known amounts of solid NaOH and measure the pH of the solution, with the results shown in the table.  Plot these values as a titration curve.  You can provide this either as a manual graph on graph paper or by using a graphing program.   Graphs done manually on regular lined paper will not be accepted.  On your graph indicate the position of where the concentration of [-OOC-COOH] = [-OOC-COO-]

B. Based on the results of the titration, what is the starting concentration of oxalic acid?  Show your work.

C. What is the net average charge/molecule at pH 4.75?  Show your work.
