New trends and techniques of the electrochemical method are reviewed to show readers how electrochemical methods gave impact to a variety of problems in today's chemistry. An emphasis was given to demonstrate the feasibility of the electrochemical method to study what can not be solved with other methods.
Contents of the present review are as follows : 1) What is the electrochemical method ?, 2) Measurements and apparatus, 3) Sample preparations, 4) Problems associated with electrochemical methods, 5) Functional electrodes, 6) Determination of thermodynamic constants, 7) New types of electrochemical reactions, and 8) Future.
