The concentration of solutes affects many colligative properties, including increasing the osmotic pressure, and causing freezing-point depression and boiling-point elevation.
12.
Osmolarity can be measured using an osmometer which measures colligative properties, such as Freezing-point depression, Vapor pressure, or Boiling-point elevation.
13.
It was invented by Ernst Otto Beckmann ( 1853 & ndash; 1923 ), a German chemist, for his measurements of colligative properties in 1905.
14.
The solute particles displace some solvent molecules in the liquid phase and therefore reduce the concentration of solvent, so that the colligative properties are independent of the nature of the solute.
15.
:: : : Freezing point depression is a colligative property, and so to a first approximation depends solely on the number of solute particles, but not on their identity.
16.
The " boiling point elevation " is a colligative property, which means that it is dependent on the presence of dissolved particles and their number, but not their identity.
17.
Specific heat depression could probably be counted among the Colligative properties of solutions for that reason .-- " 32 " 15 : 22, 14 April 2016 ( UTC)
18.
The term " cryoscopy " comes from Greek and means " freezing measurement . " Freezing point depression is a colligative property, so \ Delta T depends only on the number of solute particles dissolved, not the nature of those particles.
19.
The "'van't Hoff factor i "'is a measure of the effect of a solute upon colligative properties such as osmotic pressure, relative lowering in vapor pressure, elevation of boiling point and freezing point depression.
20.
Measurement of colligative properties for a dilute solution of a non-ionized solute such as urea or glucose in water or another solvent can lead to determinations of relative molar masses, both for small molecules and for polymers which cannot be studied by other means.
