Question

Match the examples with their respective colloidal type:

• A. Aerosol
• B. Sol
• C. Foam

Answer 1

A colloid has 2 components. The solute-like particles that are dispersed in a colloid form the dispersed phase and the component in which these particles are dispersed is known as the dispersion medium.

Fog is an example of an aerosol as the dispersed phase is in the liquid state and the dispersion medium is in the gaseous state.

Blood is an example of a sol as the dispersed phase is in the solid state and the dispersion medium is in the liquid state.

Whipped cream is an example of a foam as the dispersed phase is in the gaseous state and dispersion medium is in the solid state.
