Describe how TLC could be used to confirm whether a compound was pure or not. Were all of the standard analgesic solutions provided for you in this experiment pure?

In order to determine the purity or impurity of the substance using the TLC, the TLC plate should be developed first in a chamber and then visualizing the spots under the UV light. Thus, the pure compound can be determined when the dotted compound look as a single circle spot while the not pure compound will appear as two or more circle spots in one lane of the compounds. However, Three of the standard compounds analgesic solutions that were provided in this lab were pure expect two of them which are acetanilide and phenacetin (the unknown) were impure.
