Question

Colligative properties are applicable to-
A.Ideal dilute solutions
B.Concentrated solutions
C.Non ideal solutions
D.All of these

Answer 1

A colligative property of a solution is one that is determined by the ratio of total number of solute particles (in the solution) to total number of solvent particles. The chemical composition of the solution's components has no bearing on colligative characteristics. As a result, colligative characteristics can be related to a variety of variables that reflect a solution's concentration, including molarity, normalcy, and molality.

Complete answer:
A solution can have the following four colligative properties:
Elevation of the boiling point.
Depression at the freezing point.
Vapour pressure is reduced in a relative sense.
Osmotic pressure
Some characteristics of dilute solutions containing non-volatile solutes are dependent simply on the quantity of solute particles present, not on the kind of solute present. These are referred to as colligative characteristics. These characteristics are particularly noticeable in dilute solutions. We may also think of colligative characteristics as those that result from the dissolution of a non-volatile solute in a volatile solvent. In general, the solute alters the solvent characteristics by removing some of the solvent molecules from the liquid phase. The solvent concentration is also reduced as a result of this.
Meanwhile, colligative characteristics are stated to be inversely proportional to the solute molar mass when we talk about a particular solute-solvent mass ratio. Because colligative characteristics are based solely on the concentration of the solvent and are independent of its nature, they may be applied to concentrated, non-ideal, and ideal dilute solutions.

Hence option d is correct.

Note:
By looking at the examples below, we can see how solutions have colligative features. When a pinch of salt is added to a glass of water, the freezing temperature is significantly reduced compared to the regular temperature. Alternatively, the solution's boiling temperature is raised, resulting in a reduced vapour pressure. There are also variations in the osmotic pressure.
