This module gently introduces a topic whose mere mention often strikes fear in the hearts of students and teachers alike. Whether because of some intimidating mathematical aspects of the subject, or a lack of time to provide an adequate basis for understanding, it is often left off of course syllabi in analytical chemistry, This learning module is designed as an introduction to the underlying theory and general practice of several common techniques in analytical electrochemistry. It is intended to contain sufficient background material so that educators or new practitioners in the field can use the material in a "stand-aIone" way. References and links are provided so that users who so desire can pursue a more extensive study of each topic presented. Sufficient coverage is provided such that the module could serve as a two- to three-week segment of a course in analytical chemistry or instrumental methods.
