Chapter 14.1, Problem 5SSC

Interpretation Introduction

Interpretation:

Different types of colloids have to be described.

Concept introduction:

Colloid: A colloid is a two-phasic heterogeneous mixture where one phase is dispersed in another phase, the particle size of the dispersed phase is in between 1 nm to 100 nm. By changing the nature of dispersed phase and dispersion medium, various number of colloids were reported.

Answer to Problem 5SSC

A colloid is a two-phasic heterogeneous mixture where one phase is dispersed in another phase. Depending on nature of dispersed phase and dispersion medium colloids can be classified as sol, solid aerosol, gel, emulsion, aerosol, solid foam, foam.

Explanation:

A colloid is a two-phasic heterogeneous mixture where one phase is dispersed in another phase. Depending on nature of dispersed phase and dispersion medium colloids can be classified as follows-

Name of the Colloidal solution	Dispersed Phase	Dispersion Medium	Examples
Sol	solid	liquid	paint, blood, gelatin
Solid aerosol	solid	gas	smoke, dust in air
Gel	liquid	solid	cheese, butter
Emulsion	liquid	liquid	milk, mayonnaise
Aerosol	liquid	gas	fog, mist, clouds, aerosol spray
Solid Foam	gas	solid	marshmallow
Foam	gas	liquid	whipped cream, shaving cream

Conclusion

A colloid is a two phase heterogeneous mixture where one phase is dispersed in another phase. It can be classified as sol, solid aerosol, gel, emulsion, aerosol, solid foam, foam.
