An unknown sample arrives in a forensics lab from an accident scene. The chemical needs to be identified to determine what exposure an unconscious worker has received. The compound is known to be one of the following compounds: ethanol, t-butyl alcohol, cyclohexanol, or phenol. As the lab technician, you run a series of test on the sample to determine the identity of the substance. 1) Using your knowledge of the discipline, explain what individual tests you ran on the sample. 2) Explain how the individual tests can be used collectively to determine the identity of the unknown. What could the unknown be based on the results of the tests? Could your determination be made with less information? Why or why not?
