Current Flow in an Electrochemical Cell:
Thermodynamic arguments permit the feasibility of overall cell reactions to be predicted, but give no information on rates. To understand the latter it is necessary to consider the effects on various parts of the cell of forcing the cell voltage to assume a value different from that of the equilibrium potential Eeq (V) or electromotive force (emf). In the example of Figure 1, the cell contains hydrochloric acid as aqueous electrolyte and it divides into two compartments by a semipermeable membrane.
This book titled "Recent Trend in Electrochemical Science and Technology" contains a selection of chapters focused on advanced methods used in the research area of electrochemical science and technologies; descriptions of electrochemical systems; processing of novel materials and mechanisms relevant for their operation. This book provides an overview on some of the recent development in electrochemical science and technology.
This book introduces some basic and advanced studies on ionic liquids in the
electrochemical fi eld. Although ionic liquids are known by only a few scientists
and engineers, their applications ’ potential in future technologies is unlimited.
There are already many reports of basic and applied studies of ionic liquids
as reaction solvents, but the reaction solvent is not the only brilliant future of
the ionic liquids. Electrochemistry has become a big fi eld covering several key
ideas such as energy, environment, nanotechnology, and analysis.
Corrosion can be generally deﬁned as degradation of materials in a reaction between the material and its environment. The nature of the reactions leading to degradation depends on the class of materials: for metals, corrosion is an electrochemical process, whereas ceramics can fail by purely chemical dissolution. This article mainly discusses the corrosion processes of metallic materials, that is, electrochemical corrosion reactions.
As currently taught, the introductory course in analytical chemistry emphasizes
quantitative (and sometimes qualitative) methods of analysis coupled with a heavy
dose of equilibrium chemistry. Analytical chemistry, however, is more than equilibrium
chemistry and a collection of analytical methods; it is an approach to solving
chemical problems. Although discussing different methods is important, that discussion
should not come at the expense of other equally important topics.
