Colligative Properties | MCQs

Explanation

The property that does not depend on the nature of the solute molecule is the Colligative property. 

Colligative properties depend solely on the number of solute particles present in a solution, not their identity or chemical nature. 

Explanation

Colligative properties are properties of solutions that depend on the number of solute particles in a given amount of solvent and not on the nature of the solute particles.

The four main colligative properties are:

• Vapor Pressure Lowering
• Boiling Point Elevation
• Freezing Point Depression
• Osmotic Pressure

Explanation

• When salt is added to pure water, the boiling point of the solution increases. This is known as boiling-point elevation.
• The boiling point of a solution is higher than that of the pure solvent (water) because the dissolved salt particles disrupt the formation of vapor bubbles, requiring more energy to overcome the surface tension and escape the solution as vapor.
