Question

How are sol, solution and suspension different from each other?

Answer 1

Hint: We have to know about mixture and their different compositions. We can define mixture as an entity that contains two (or) different substances, which are joined chemically.
Example: On mixing powdered iron and powdered sulphur, we could get a mixture of iron and sulphur.

Complete step by step answer:
We can classify mixtures as homogeneous mixture and heterogeneous mixture.
Homogeneous mixture is a type of mixture, in which part of the solution has like properties and uniform composition. Example: Water and sugar.
Heterogeneous mixture is a type of mixture, in which the particles can be separated from each other by physical process. Example: Salt and pepper.
Now let us define solution, sol and suspension.
We can define a homogeneous mixture of two (or) substances as a solution.
A heterogeneous mixture is a sol. Suspension is a heterogeneous mixture and is unstable in nature.
Now we can differentiate between sol, solution and suspension.
Sol- Sol is a heterogeneous mixture. The particle size is Sol exhibits Tyndall effect and they appear glassy and clear. They undergo slow diffusion and are quite stable. The particles are settled on centrifugation.

Solution- Solution is a homogeneous mixture. The particle size is less than 1nm Solution does not exhibit Tyndall effect and they appear unclouded and clear. They undergo rapid diffusion and are highly stable. The particles do not settle.

Suspension- Suspension is a heterogeneous mixture. The particle size is more than 100nm. Based on the mixture type, suspension does not/does exhibit Tyndall effect and they appear cloudy and opaque. They do not undergo diffusion and are unstable. The particles settle by themselves.

Note:
Some of the examples for Sol are milk, blood and smoke. Similarly a solution of sugar and salt are examples of solution. Dusty airs, sand in water are the examples of suspension.
