Abstract. This paper describes an junior/senior level undergraduate laboratory for analytical or physical chemistry that can be used to demonstrate how self-assembled monolayers (SAM) form and pack onto a surface. The laboratory experiment will also introduce students to electrochemical techniques, instrumentation and surface analysis techniques. The two-part experiment first uses chronocoulometry to determine the surface area of an electrode. The second part uses the area of the electrode in conjunction with a SAM to determine the surface coverage and packing of the SAM. The students learn to operate the potentiostat, clean and prepare gold electrodes, and use common electrochemical techniques.
