Processes that take place at a phase boundary connected with the transfer of electric charge - the electrode processes - are of great importance in many aspects of everyday life. Nevertheless, the elaboration of theories concerning these processes started only in the 1930s. In particular, results obtained during the last two decades have made it possible to survey the general theoretical fundamentals of electrode processes and to elucidate the reaction mechanisms of several important electrode processes. The main aim of the present work is to describe the most significant kinetic characteristics of an important group of electrode processes - the electrochemical dissolution of metals (anodic and spontaneous dissolution). An overview is given on the kinetics of the complex processes taking place in consecutive and parallel reaction paths. In this respect the book fills a gap, as it is the first time that a work relevant to the stepwise mechanism of electrode processes has been published. The value of the work is enhanced by the inclusion of the author's own results, which are assessed together with those of other research workers.
