Question

Distinguish between Colloid and Suspension.​

Answer 1

Answer:

Suspension Colloid

It is a form of the heterogeneous solution It is a form of a homogeneous solution

Particle size greater than 1000 nm Particle size range from 1 and 1000 nm

Particles settle down well Particles do not separate

Answer 2

Explanation:

suspension is defined as a homogenous mixture of particles with a diameter greater than 1000 nm such that the particles are visible to naked eyes. In this type of mixture, all the components are completely mixed and all the particles can be seen under a microscope. A suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation.

Suspension & Precipitation

If we take a glass full of water and mix mud in it, it will form a heterogeneous mixture. We can easily identify the components of these mixtures. After some time we will observe that particles of mud settle down due to gravity. The particles in suspension are larger than the particles in a solution.

Colloid is an intermediate between solution and suspension. It has particles with sizes between 2 and 1000 nanometers. A colloid is easily visible to the naked eye. Colloids can be distinguished from solutions using the Tyndall effect. Tyndall effect is defined as the scattering of light (light beam) through a colloidal solution. The particles are termed as colloidal particles and the mixture formed is known as colloidal dispersion. Liquid, solid and gases all mix together to form a colloidal dispersion.

Examples of Colloids

The different types of colloidal solution are:

Aerosols: Solid or liquid mixed with gas; Example: fog (liquid in gas)

Sols: Solid mixed with liquid; Example: Paint

Emulsion: Liquid with liquid; Example: oil and water

Gel: liquid in solid; Example: Fruit jelly
