Abstract. This paper describes an undergraduate laboratory for an electroanalytical chemistry course that can be used to supplement the teaching of oxidation and reduction reactions. The laboratory also introduces basic electrochemical techniques, instrumentation, and the preparation of a conducting polymer film, poly(3-methylthiophene), as a chemical sensor for the detection of catechol in the presence of a common interferent, ascorbic acid.

Key Words: In the Classroom; analytical chemistry; electrochemistry, ascorbic acid
