Post Laboratory Questions:
1. For each of the following situations, describe what effect the following occurrences would have
on your measurement of the solution concentration by titration. Would the "calculated"
concentration come out too low, too high, or just right when compared to the "true"
concentration? Explain briefly.
a. You rinse the buret with water, instead of HCl before adding the HCl to the buret for
titration.
b. You don't notice the color change until several drops after the color change has occurred.
c. The volumetric pipet fails to deliver the full 5.00 mL of your sample to the flask.
d. In Step 4, you added 30 mL of water to titration flask instead of the 25 mL called for.
e. You misread the buret and have actually delivered 0.05 mL less HCl than you recorded.
