What is the difference between colloids and colloidal solutions Relate...
Colloids or Colloidal Solution:
Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid. A colloid is a very tiny and small material that is spread out uniformly all through another substance.
Colloidal systems can occur in any of the three key states of matter gas, liquid or solid. However, a colloidal solution usually refers to a liquid concoction. The primary distinguishing feature between a true solution and a colloidal solution is fundamentally the dimensions of the constituent parts.
True Solution and Colloidal Solution
In a true solution, like salt water, NaCl molecules are totally mixed in the water, and the solution can pass through a semi-permeable film without getting divided. On the other hand, in a colloidal solution, the units are bigger and they don’t liquefy. However, they are equally dispersed all through a liquid. As such these units will not pass through a membrane as the liquid does.
