Question

How are colloids classified on the basis of (i) Physical states of components (ii) Nature of dispersion medium and (iii) Interaction between dispersed phase and dispersion medium?

Answer 1

Hey Dear,

◆ Classification of colloids -

(i) Based on physical states of components -

1. Gas in liquid - aerosol
2. Gas in liquid - aerosol
3. Liquid in gas - foam
4. Liquid in liquid - emulsion
5. Liquid in solid - sol
6. Solid in gas - solid foam
7. Solid in liquid - solid emulsion
8. Solid in solid - solid sol

(ii) Based on nature of dispersion medium -

1. Water - aquasol
2. Alcohol - alcosol
3. Gases - aerosol
4. Benzene - benzosol

(iii) Based on interaction between dispersed phase and dispersion medium -

1. Attraction - lyophilic
2. Repulsion - lyophobic

Thanks dear...

Answer 2

Answer:

(ii) Classification based on Nature of interaction between dispersed phase and dispersion medium:

• Depending upon the nature of interactions between dispersed phase and the dispersion medium

• the colloidal solutions can be classified into two types as (a) Lyophilic and (b) Lyophobic sols.
