Instructor Graded

The following questions will be graded manually by your instructor. You can edit your submission up until the deadline for this assignment.

Hint: You may wish to make a 0.1000 M solution of your unknown and transfer 20 mL of that solution to a 250 mL volumetric flask. You will titrate this solution with the stock 0.1000M NaOH. Before doing your titration, predict at what volumes the first and second equivalence points will occur. You can titrate in increments of 1 mL until you are within a mL of an endpoint. At that time you should reduce the volume to 0.1mL and use this small quantity until you are a mL beyond the endpoint. Then you can revert back to 1 mL increments until you reach the second endpoint or have completed the titration.
