colligative


Also found in: Dictionary, Encyclopedia, Wikipedia.

col·li·ga·tive

(ko-lig'ă-tiv),
1. Depending on numbers of particles.
2. Referring to properties of solutions that depend only on the concentration of dissolved substances and not on their nature (for example, osmotic pressure, elevation of boiling point, vapor pressure lowering, freezing point depression).

colligative

[kol′igā′tiv]
Etymology: L, colligere, to gather
(in physical chemistry) pertaining to those properties of matter (especially solutions) that depend on the numbers of particles, such as molecules and ions, rather than the chemical identity of any one particle. Colligative properties of solutions include boiling point, freezing point, vapor, pressure, and osmotic pressure.

The 28 experiments include specific heats of substances, chromatography, reaction stoichiometry, gravimetric analysis of a chloride compound, the concentration of acetic acid in vinegar, colligative properties, and gas laws.
In practice, these water contents are considered to be negligible, since the osmotic pressure of many solutions increases more than linearly with concentration, and because of colligative properties of the cellular ultrastructure.
The Solubility module covers a wide range of concepts: vapor pressure and solution equilibrium, molecular solvation, and factors affecting solubility, miscibility, dispersion, and colligative properties of solutions.
