Question

What type of colloid is smog

Answer 1

Smog is a colloidal mixture (aerosol) of liquid and solid particles dispersed in a gas.

Explanation:

• A colloid is a colloidal dispersion of a two-phase heterogeneous mixture made up of a dispersed phase of tiny particles that are distributed evenly within a continuous phase.
• Here, the dispersed phase is the liquid phase and the dispersion medium is a gaseous component.
• Smog = Smoke + Fog
• Smog is a type of air pollution, also known as a liquid aerosol.
• Smog is a concentrated slowly moving colloidal mixture over the atmosphere, that diminishes visibility.
