Introductory Electrochemistry and Related Applications Maurice Iwunze

This monograph is an introductory text of electrochemistry for students of Science, Technology and Engineering at the very elementary level (Second year University students and their equivalent counterparts in Technical and Teachers Training Colleges). It may also be used as a refresher for upper level students at these institutions. The science of electrochemistry has undergone very dramatic changes in the past fifty years and its slow development at an earlier stage was due mainly to the fact that Nernstian equilibrium treatment of the subject does not tell the whole truth about electrochemical systems and their reactions. Application of kinetics to the study of electrochemistry has accelerated the pace and its eventual recognition as an important branch of science in its own right. Despite this recognition, elementary textbooks at the first Year University degree program levels have tended to treat this branch of science with cursory and utmost brevity. The unfortunate consequence of this is that students are not fully aware of the important technology that goes along with electrochemistry. These students are, perhaps, aware only of the Nernstian relationship and just the vague notion of accumulator cells. The aim of this monograph therefore is both to enlighten and to heighten the inquisitive and, I dare say, enthusiastic minds of the young students who may wish to know more about the important fundamentals and application of this branch of science. Chapters one and two of this short monograph are merely a revision and recapitulation of the basic information. Chapter three discusses the application of the electrochemical theory. Different battery systems, their manufacture and assembly are discussed. Fuel cell technology is also discussed. The very important analytical techniques, potentiometry/ion selective electrode is briefly mentioned.
