Question

Determine whether each of the examples represents a colligative property or a non-colligative property. boiling point elevation Choose... color Choose... freezing point depression Choose... vapor pressure lowering Choose... density Choose...

Answer 1

Answer:

boiling point elevation - colligative property

color - non-colligative property

freezing point depression - colligative property

vapor pressure lowering - colligative property

density - non-colligative property

Explanation:

A colligative property is a property that depends on the number of particles present in the system.

Freezing point depression, boiling point elevation and vapour pressure lowering are all colligative properties of solutions.

Colour and density do not depend on the number of particles present hence they are not colligative properties.

Answer 2

The boiling point elevation, freezing point depression, and vapor pressure lowering are colligative properties. And color and density are non-colligative properties.

Explanation:

• The colligative properties are the properties depending upon the number of particles of solute not on the nature of the solute.
• Example of colligative properties:

1. Vapor pressure lowering
2. Elevation boiling point
3. Depression in freezing point
4. Osmotic pressure

• The non-colligative properties are the properties depending upon the nature of solute and solvent.
• Example of non-colligative properties :

1. Viscosity
2. Surface tension
3. Density
4. Solubility

So, from this, we can conclude that boiling point elevation, freezing point depression, and vapor pressure lowering are colligative properties. And color and density are non-colligative properties.
