Question

How can we separate particles of a colloidal solution? Name the process.

Answer 1

A solution is a homogeneous mixture of solute and solvent. A colloidal solution is a solution consisting of suspended particles that are continuously dispersed. By using a high rotatory or centrifuge machine the particles that differ in size can be separated.

Complete answer:
Chemical compounds can be dissolved or soluble in one another by forming solutions. The solution is a homogeneous mixture of solvent and solute. The solute dissolves in the solvent uniformly.
The colloidal solution is also one of the solutions in which the suspended particles can be continuously dispersed but not settle down. In the suspensions, the suspended particles may settle down.
Colloids are also known as colloidal suspension or colloidal solution. In colloidal solutions, the size of the particles may range from $1nm$ to $500nm$ . As the colloidal solution consists of a mixture of particles. These particles can be separated based on rotation.
When the colloidal solution is kept in a high-speed rotation machine or centrifuge machine. The particles which are denser will be at the bottom only and the lighter particles stay at the top only.
Thus, by the process of centrifugation, we can separate particles of a colloidal solution.

Note:
Centrifuge machines have so many applications in daily life also. To check the quality of colloidal solutions like milk it can be used. As the milk particles are denser and settle down, whereas the water in milk is less dense and stays at the top.
