Over the past century, numerous aspects of the reaction between urea and hypobromite have been exploited to quantify urea in clinical and industrial process samples. A review of these analytical approaches provides an interesting illustration of changes in a chemical system that indicate a reaction has occurred-the production of a gas, a color change, the release of heat, and the emission of light-and a variety of instruments that were developed to measure these changes and quantify a reacting species. In this paper we describe how we have used this material in a tutorial class for first-year undergraduate (freshman) students and a follow-up assignment, which we have included in the supporting material. In addition to the concepts exemplified by the above phenomena, we discuss the reaction pathway, which includes examples of ion and atom transfer. These are often overlooked in favor of electron transfer in the teaching of redox chemistry.
