This book reflects experience of Southampton Electrochemistry Group in presenting under-graduate and post-graduate and also one-week Summer School industrial courses. This study of the problems in chemistry, materials science and their technology explains the fundamentals and applications of electrochemistry required for an understanding of the laboratory experiments It presents a balanced view of instrumental techniques, the electronics and the approach to data treatment which can be helpful to users of electrochemical methods. Alternate chapters develop the fundamentals of electrochemistry, and discuss electrochemical techniques. Later chapters introduce concepts in qualitative and quantitative ways, presenting the equations for used converting experimental data into physical parameters and discussing experimental details. Numerous diagrams illustrate examples of applications of the techniques. The book is helpful to students reading chemistry, working electrochemists, and non-specialists wishing to enter the field. The Southampton Electrochemistry Group responsible for compiling and editing this book then consisted of: R. Greef, R. Peat, L. M. Peter, D. Pletcher and J. Robinson.
