What is Rf Values for Aspirin and Acetaminophen about?

Samples of aspirin, acetaminophen solution, caffeine, and two unknowns (A and B) were tested in thin layer chromatography to determine their Rf values and identify the unknowns. Unknown A was found to have the same Rf value as acetaminophen solution of 0.23, so it was identified as acetaminophen solution. Unknown B had an Rf value of 0.63 matching aspirin, so it was identified as aspirin.
