Which of the following is a colligative property of a solution?
A
Density
B
Color
C
Boiling point elevation
D
Viscosity
Verified step by step guidance
1
Understand that colligative properties depend on the number of solute particles in a solution, not on their identity or type.
Recall the common colligative properties: vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
Analyze each option: Density depends on mass and volume, Color depends on the nature of solute, Viscosity depends on intermolecular forces, and Boiling point elevation depends on the number of solute particles.
Recognize that boiling point elevation is a classic colligative property because it changes based on the concentration of solute particles in the solvent.
Conclude that among the given options, boiling point elevation is the correct colligative property.
