Question

List any four properties of a colloid and mention any two properties in which colloids differ from suspension ​

Answer 1

Answer:

properties of colloid

• it is a heterogeneous mixture
• if particles are too small to visible
• they scatter a Ray of light

do do not settle down when kept at rest so there stable

• colloidal particles are not visible but suspended particles are visible
• colloidal particles do not settle down but suspended particles either float or settle down

Answer 2

Explanation:

Properties of a Colloid

1. Collide is a heterogeneous mixture of a dispersed phase and a dispersion medium but due to small particle size, it appears as a homogeneous mixture to the naked eye.
2. The particle size varies from 1 to 100 nm (nano meters).
3. The particles of a colloid pass through filter paper, which means that they can not be separated by filtration.
4. Colloids are stable, that is, their particles don't settle down when left undisturbed for some.

Properties of a Suspensio

• Suspensions are heterogeneous mixtures of solute and a solvent.
• Their particle size is greater than 100 nm and their particles ca be seen with the naked eye.
• The particles of a suspension don't pass through filter paper, which means hat their particles can be separated by filtration.
• Suspensions aren't stable, that is, their particles settle down when left undisturbed for some time.
