Martínez-Balbuena and others published Applicability of the Gibbs Adsorption Isotherm to the analysis of experimental surface-tension data for ionic and nonionic ... The Gibbs adsorption isotherm for multicomponent systems is an equation used to relate the changes in concentration of a component in contact with a surface with changes in the surface tension, which results in a corresponding change in surface energy. For a binary system, the Gibbs adsorption equation in … See more Different influences at the interface may cause changes in the composition of the near-surface layer. Substances may either accumulate near the surface or, conversely, move into the bulk. The movement of the … See more Location of surface In the presence of two phases (α and β), the surface (surface phase) is located in between the phase α and phase β. Experimentally, it is … See more Gibbs equation for electrolyte adsorption Consider a system composed of water that contains an organic electrolyte RNaz and an inorganic electrolyte NaCl that both dissociate … See more Surface tension describes how difficult it is to extend the area of a surface (by stretching or distorting it). If surface tension is high, there is a large free energy required to increase the surface area, so the surface will tend to contract and hold together like a … See more Derivation of the Gibbs adsorption equation For a two-phase system consisting of the α and β phase in … See more The extent of adsorption at a liquid interface can be evaluated using the surface tension concentration data and the Gibbs adsorption … See more WebThe relationship between standard Gibbs free energy change and the equilibrium constant K.
