This edition provides a comprehensive introduction to electrochemistry in a manner that is readily accessible to undergraduates in chemistry and related fields. Principles and applications are now separated in this revision. The work has been re-organized to give greater prominence to areas such as electrochemical sensors and electroanalytical techniques; a number of modern electroanalytical methods not included in previous editions are also featured. A range of numerical problems and outline solutions is provided for each chapter to cover most situations that a student might encounter.
