Equilibrium constant — For a general chemical reaction:alpha A +eta B ... ightleftharpoons sigma S+ au T ...the equilibrium constant can be defined by [F.J,C. Rossotti and H. Rossotti, The Determination of Stability Constants, McGraw Hill, 1961.] :K=frac{S ^sigma {{T^ … Wikipedia
Activity coefficient — An activity coefficient [ [http://www.iupac.org/goldbook/A00116.pdf Gold Book definition] ] is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances. In an ideal mixture the… … Wikipedia
Determination of equilibrium constants — Equilibrium constants are determined in order to quantify chemical equilibria. When an equilibrium constant is expressed as a concentration quotient, it is implied that the activity quotient is constant. In order for this assumption to be valid… … Wikipedia
Activity (chemistry) — In chemical thermodynamics, activity (symbol a) is a measure of the “effective concentration” of a species in a mixture, meaning that the species chemical potential depends on the activity of a real solution in the same way that it would depend… … Wikipedia
Chemical equilibrium — In a chemical reaction, chemical equilibrium is the state in which the concentrations of the reactants and products have not yet changed with time. It occurs only in reversible reactions, and not in irreversible reactions. Usually, this state… … Wikipedia
Acid dissociation constant — Acetic acid, a weak acid, donates a proton (hydrogen ion, high … Wikipedia
Solubility equilibrium — is any type chemical equilibrium between solid and dissolved states of a compound at saturation. Solubility equilibria involve application of chemical principles and constants to predict solubility of substances under specific conditions (because … Wikipedia

PH — is the measure of the acidity or alkalinity of a solution. It is formally a measure of the activity of dissolved hydrogen ions (H+), but for very dilute solutions, the molarity (molar concentration) of H+ may be used as a substitute with little… … Wikipedia
Nernst equation — In electrochemistry, the Nernst equation is an equation that can be used (in conjunction with other information) to determine the equilibrium reduction potential of a half cell in an electrochemical cell. It can also be used to determine the… … Wikipedia
acid–base reaction — ▪ chemistry Introduction a type of chemical process typified by the exchange of one or more hydrogen ions, H+, between species that may be neutral (molecules, such as water, H2O; or acetic acid, CH3CO2H) or electrically charged (ions, such… … Universalium
