The properties of solution that only depends on the number of source particles are called Collegative Properties

In chemistry,colligative propertiesarepropertiesof solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the chemical species present. ... The wordcolligativeis derived from the Latin colligatus meaning bound together.

Inchemistry,colligative propertiesare properties ofsolutionsthat depend on the ratio of the number of solute particles to the number ofsolventmoleculesin a solution, and not on the nature of the chemical species present.[1]The number ratio can be related to the various units forconcentrationof solutions, for example,molarity,molality,normality (chemistry), etc. The assumption that solution properties are independent of nature of solute particles is only exact forideal solutions, and is approximate for dilute real solutions. In other words, colligative properties are a set of solution properties that can be reasonably approximated by assuming that the solution is ideal.

Colligative property are those properties which depend upon the number of particles of solute contained in a known volume of a given of a given solvent and are independent of the chemical composition or nature of solvent.

The properties which only depends on the amount of substance irrespective of the nature of the substance
