Electrolyte solutions, the dipole moment of two unit charges, of opposite sign and at a separation of 1 Å, has a value of . Cm. Good solvents typically have dipole moments that are only a little lower. The resulting strong electrostatic interaction between the molecules is usually the reason, why these substances are liq

A few basic concepts,ok. In particular we will illuminate the relation of electrochemical concepts to those used in related disciplines. Electrochemistry has much in common with surface science, which is the study of solid surfaces in contact with a gas phase or, more commonly, with ultrahigh vacuum (uhv). A number of s

Adsorption on metal electrodes: principles,rption. It is usually caused by chemical interactions between the adsorbate and the electrode, and is then denoted as chemisorption. In some cases adsorption is caused by weaker interactions such as van der Waals forces; we then speak of physisorption. Of course, the solvent is always present at the

Adsorption on metal electrodes: examples,orbate – adsorbate. Because of their weak solvation shells, anions adsorb easily on metal surfaces, particularly at potentials positive of the pzc. However, it is not easy to determine the coverage. Often the adsorbed ions carry a partial charge, they repel each other, and the coverage increases onl

Thermodynamics of ideal polarizable interfaces,] and Parsons and, like all proper thermodynamics, is exact. However, our way of defining the surface tension and deriving its differential is different, and is based on a discussion with H. Ibach, whose book contains an alternative derivation directed at solid electrodes . In the classical d

Phenomenological treatment of electron-transfer reactions,ves at least one electron-transfer step. This is even true if the current across the electrochemical interface is carried by ions since, depending on the direction of the current, the ions must either be generated or discharged by an exchange of electrons with the surroundings.

Theoretical considerations of electron-transfer reactions,ficiently simple that we have reached a fair understanding of them in terms of microscopic concepts. In this chapter we give a simple derivation of a semiclassical theory of outer-sphere electron-transfer reactions, which was first systematically developed by Marcus and Hush in a series of pap

The semiconductor-electrolyte interface,eactions are used in the production of semiconductor chips, and recently semiconductors have been used in the construction of electrochemical photocells. So there are good technological reasons to study the interface between a semiconductor and an electrolyte. Our main interest, however, lies in mor
