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.

Sweeteners functionalities--which include sweetness, flavor and flavor enhancement, freezing point depression, boiling point elevation, caramelization, texturization, moisture management, and heat of dissolution--are largely determined by the size, molecular weight, solubility and colligative properties of the agent in question.
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.
Our attempt to "narrativize" this complex set of events within the contingent and colligative bounds of a "story" is not to be read as an authoritative account of what actually took place in the oil industry in the 1970s and 1980s.
Methods based on colligative properties like osmotic pressure, and Raoult's law yield the number average molecular weight, whereas light scattering methods yield the weight average molecular weight.
Fiser and Fairfull (1986) stated that glycerol provides cryopreservation partly on a colligative basis by reducing the amount of ice formation and partly kinetically by increasing the time for water to leave the cell in response to the decreased vapor pressure of adjacent ice.
Recognizing that DMSP is employed by some organisms to help set the colligative properties of cellular solutions, Nishiguchi and Somero (1992) studied the effects of DMSP on cellular proteins.
