Electrochemistry of Metal Complexes: Applications from Electroplating to Oxide Layer Formation

A systematic analysis of electrochemical processes involving metalcomplexes. Starting with general considerations on equilibria in solutions andat interfaces as well as on mass transport, the text acquaintsreaders with the theory and common experimental practice forstudying electrochemical reactions of metals complexes. The corepart of the book deals with all important aspects ofelectroplating, including a systematic discussion of co–depositionof metals and formation of alloys. It also discusses such relatedsubjects as oxide layer formation and hydrogen evolution as a sidereaction.
