  • 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 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.

  • Introduction: 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.

  • The corrosion inhibition of mild steel in 0.01M HCl acid solution by water extract of Green tea has been studied using electrochemical method. The results of the study reveal that the inhibition efficiency of the extract is found to vary with concentration and period of immersion. Thermodynamic consideration reveals that adsorption of Green tea extract on mild steel surface is spontaneous and occurs according to Langmuir adsorption isotherm. Physical adsorption mechanism has been proposed for the adsorption of the inhibitor from the values of some kinetic and thermodynamic parameters.

  • 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.
