Question

explain Lyophilic as and Lyophobic sols​

Answer 1

Answer:

here you go

Explanation:

In lyophilic sols, the dispersed phase particles have great affinity for the dispersion medium. These sols are reversible. Examples include gum, gelatin, starch, proteins and rubber etc.

In lyophobic sols, the dispersed phase particles have no affinity for the dispersion medium. These sols are irreversible. Examples include solutions of metals such as gold and silver, metal hydroxides and metal sulphides.

Answer 2

Answer:

Explanation:

lyophilic sols

• solvent loving.
• here colloidal particles are easily solvated.
• small quantities of electrolyte have a little effect but large amount may cause salting out.
• the particle can't be readily detected in ultra microscope.
• particles may migrate in either direction or not at all in an electric field.
• surface tension is generally lower than that of dispersion medium.
• they are reversible
• viscosity is much higher than that of the medium.

lyophobic sols

• solvent hating
• colloidal particles are weakly solvated
• small quantities of electrolyte causes precipitation
• particles are easily detected
• particle migrate in only one direction in an electric field.
• surface tension and viscosity are almost similar to that of dispersion medium
• they are irreversible
