Abstract. A An experiment is described in which a diazonium salt is prepared and then used to synthesize three separate products. One part of the experiment involves preparation and evaluation of the acid-base indicator known as Methyl Red. A second azo compound is also prepared and isolated. Hydrolysis of the intermediate diazonium salt to yield a phenol is also described.
