The experiment wAs preformed using a recrystallization of salicylic acid. The IR was preformed using a KBR pellet method Re-state the diagnostic peaks from the results, this time with the intention of comparing the experimental to literature diagnostic values as well as fingerprint regions to provide evidence to answer your hypothesis. After comparing your values, you must discuss what conclusions you obtained (i.e. was there evidence to support that your compound is pure?)
