Question

Can colloids be separated?

Answer 1

Colloids:

1. A colloid is a homogeneous mixture of particles with sizes ranging from $1$to $1000nm$ in diameter, dispersed in solution.
2. As the size of particles of the colloidal mixture have a wide range so they can be separated by centrifugation.
3. In centrifugation, the colloidal solution is kept at high rotation in the machine, due to which the dense particles settle and lighter particles keep on floating.
4. This way the particles can be separated in a colloidal solution.
