COLLIGATIVE PROPERTIES

ABSTRACT

In chemistry, colligative properties are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the type of chemical species present. The number ratio can be related to the various units for concentration of solutions. The independence of the nature of solute particles is exact for ideal solutions, and approximate for dilute real solutions. Here we consider only those properties which result because of the dissolution of nonvolatile solute in a volatile liquid solvent. They are independent of the nature of the solute because they are due essentially to the dilution of the solvent by the solute.
