Critical solution temperature is the temperature at which complete miscibility is reached as the temperature is raised or in some cases lowered —used of two…

When two pure substances mix under normal conditions there is usually an increase in the entropy of the system. In thermodynamics, the entropy of mixing…

An activity coefficient is a factor used in thermodynamics to account for deviations from ideal behavior in a mixture of chemical substances. The set of…

In chemistry, an ideal solution or ideal mixture is a solution in which the gas phase exhibits thermodynamic properties analogous to those of a mixture…

An alloy is a combination of metals or metals combined with one or more other elements. It is a substance made by melting two or…

Alloy broadening is independent of temperature and can broaden the line-width to 2 to 5 times of its thermally broadened value. It is a spectral-line…

Isomers are molecules that have the same molecular formula but have a different arrangement of the atoms in space. A structural isomer, or constitutional isomer,…

The neutral molecules or ions (or atoms or group of atoms) which are directly attached to the central metal ion or atom through co-ordinate bonds…

Fluxional molecules are molecules that exhibit rapid intramolecular rearrangements among their component atoms. They are molecules that undergo dynamics such that some or all of their…

Coordination isomerism is a form of structural isomerism in which the composition of the complex-ion varies. It is a form of structural isomerism in which…

Electromerism a type of tautomerism in which the isomers (electromers) differ in the distribution of charge in their molecules. It is a type of isomerism…

Vitamer is one of two or more related chemical substances that fulfill the same specific vitamin function. A vitamer of a particular vitamin is any…
