Question

Is air a colloid or suspension?

Answer 1

Hint :In order to answer this question, to know whether an air is a colloid or suspension, we will explain it with a suitable reason behind it. And then we will discuss the colloid and suspension separately to understand the given question conveniently.

Complete Step By Step Answer:
Dust-free air is a real solution, whereas dust particles and water vapour are present in air, making it a colloid (aerosol). A solution is a single-phase mixture of two or more components. Suspension is a mixture of bigger particles that is heterogeneous.
A gaseous solution is made up of air oxygen and other gases dissolved in nitrogen. Non-condensable gases produce highly simple solutions despite the fact that interactions between gaseous molecules have essentially no function.
Air is a gaseous substance made up of nitrogen, oxygen, and small amounts of other chemicals. Salt, sugar, and a variety of other chemicals dissolve in water to form homogenous mixes. A homogeneous mixture is often a solution that contains both a solute and a solvent.
Smoke is made up of a variety of particles dispersed in the air. Water and other particles are mixed together in tap water. Liquids, gases, and solids are all examples of mixtures. A COLLOID is a homogeneous solution with a particle size that falls between that of a solution and that of a suspension. The particles are evenly distributed across the dispersion medium, which might be a solid, liquid, or gas.

Note :
The Tyndall effect can be used to identify colloids from solutions. A light beam travelling through a real solution, such as air, is undetectable. The larger particles will reflect light travelling through a colloidal dispersion, such as smoky or foggy air, and the light beam will be visible.
