Write any four differences between lyophilic sols and lyophobic sols

Hint: Sols are basically colloidal mixtures where the dispersed phase is a solid and the dispersion medium is a liquid. These sols can be differentiated into main types such as: lyophilic sols and lyophobic sols.

Complete step by step answer:
Before we move forward with the solution of the question, we must first understand some basic important concepts.
When discussing the term lyophobic sols, let us break down the word. ‘Lyo’ means solvent while ‘phobic’ means ‘scared of’. If we put these words together, then it means ‘scared of solvent’. This can be simply explained as a sol which is scared of or repels any solvent.
On the other hand, when discussing the term lyophilic sols, let us break down the word. ‘Lyo’ means solvent while ‘philic’ means ‘loving’. If we put these words together, then it means ‘solvent loving’. This can be simply explained as a sol which is readily acceptable of mixing with another solvent.


Note:
Some examples of lyophilic sols are gum, gelatin, starch, proteins, rubber, etc. On the other hand, some examples of lyophobic sols are metal in water, ferric hydroxide sol, sulfur etc.
