Solution of Gas in Solid Gases are always taken up by solids but the extent of uptake varies widely. It the uptake is by adsorption…

Validity and Limitations of Henry’s Law Henry’s law is obeyed fairly satisfactorily by many gases of low solubility, provided the pressure is not too high…

Influence of Pressure on Solubility The solubility of gases in liquids is greatly influenced by pressure and in all cases the solubility increases with increase…

Effect of Temperature on Solubility The solubility of a gas in a liquid is markedly affected by temperature. Usually, the solubility decreases with the increase…

Units of Concentration Whenever the concentration of a solution is reported, the appropriate unit in which it is given is also mentioned. In chemical literature…

Solution of Gas in Liquids All gases are more or less soluble in liquids. The quantity of the gas dissolved under identical conditions of temperature,…

A solution is a system one comes across every day; it is so well known that it needs no explanation. If a little sugar is…

Standard free energy change and equilibrium constant Similar to standard enthalpy of formation of compounds, the standard free energy of formation, ∆Gf0 of compounds have…

Helmholtz free energy (work function) and its significance In thermodynamics, the Helmholtz free energy is a thermodynamic potential that measures the “useful” work obtainable from…

The Free Energy and the Work Function We have already established the criterion of spontaneous processes and equilibrium. Spontaneous processes, whether chemical or physical, often…
