Question

By giving two characteristics define the suspension.

Answer 1

Suspension:

A heterogeneous mixture is called suspension when particles of solute do not dissolve but get suspended throughout the solvent.

For example, a mixture of chalk powder in water, a mixture of sand in water

Characteristics of colloidal solution:

• It is a type of heterogeneous mixture
• In a suspension particles of the solute do not dissolve in the solvent, they remain suspended throughout the solvent
• The size of particles of suspension is greater than$1nanometer\left({10}^{-9}m\right)$, so it can be visible from naked eyes.
• It shows the Tyndall effect because of their large size of particles.

Conclusion:

A heterogeneous mixture is called suspension when particles of solute do not dissolve but get suspended throughout the solvent.
