The most direct way of measuring the activity of a volatile species is to measure its equilibrium partial vapor pressure. For water as solvent, the water activity aw is the equilibrated relative humidity. For non-volatile components, such as sucrose or sodium chloride, this approach will not work since they do not … See more In chemical thermodynamics, activity (symbol a) is a measure of the "effective concentration" of a species in a mixture, in the sense that the species' chemical potential depends on the activity of a real solution in the same … See more Chemical activities should be used to define chemical potentials, where the chemical potential depends on the temperature T, pressure p and the activity ai according to the formula: where R is the See more • Equivalences among different forms of activity coefficients and chemical potentials • Calculate activity coefficients of common inorganic electrolytes and their mixtures • AIOMFAC online-model: calculator for activity coefficients of inorganic ions, … See more The relative activity of a species i, denoted ai, is defined as: $${\displaystyle a_{i}=e^{\frac {\mu _{i}-\mu _{i}^{\ominus }}{RT}}}$$ where μi is the (molar) See more Gases In most laboratory situations, the difference in behaviour between a real gas and an ideal gas is … See more • Chemistry portal • Fugacity, the equivalent of activity for partial pressure • Chemical equilibrium • Electrochemical potential • Excess chemical potential See more WebLesson Topic: W a t e r a s a S o l ve n t Objective: S t u d e n t s wi l l b e a b l e t o : 1 .
