Prompt:
Write an analysis of the quality of the information recorded in the student lab notebook for the titration experiment. Include in your discussion an explanation of any problems that would be encountered by someone trying to use the information to calculate the concentration of the acid.

Sample Response:
The acid being analyzed was not identified, so the balanced chemical equation could not be written. The volume of the pipet used to transfer the acid was not recorded, which makes it impossible to determine the molarity of the acid. The buret readings were not recorded to the nearest 0.01 mL. Units were not recorded in the data table. The buret was not rinsed with base before filling, which could dilute the base solution.
