Chem1 Introduction to Electrochemistry

The twelve lessons in this unit cover all aspects of introductory electrochemistry as the subject is usually presented in General Chemistry courses at the college and university level. Within this scope, however, the coverage is far more thorough than most courses and textbooks provide. In part this reflects the author's experience that merely getting students to draw pictures of cells and to set up and use the Nernst equation do not, in themselves, guarantee more than a superficial understanding of electrochemistry. In most courses there is simply not enough time to take the class through the details required to develop a thorough understanding of the subject even at the elementary level.

These lessons place a great deal of emphasis on developing the fundamental concepts, and in linking them with applications such as corrosion, membrane potentials and potentiometry. Although they are intended primarily for use in a General Chemistry course, the electrochemistry lessons should serve as a review and a basis for further work in more advanced courses in analytical and physical chemistry.
