classification of colloids

What are 4 types of colloids give its meaning?
Types of Colloids
Sol – It is a suspension of minute solid particles in a liquid.
Emulsion – It is a colloid between two or more liquid with one consisting a dispersion of another liquid.
Foam – It consists of gas dispersed in solid or liquid.
Aerosol – It consists of a minute liquid or solid particles in a gas.
Colloids are classified on the basis of physical states of components, that is, on the basis of physical states of the dispersed phase and dispersion medium.
Colloidal solution is classified into eight types of colloidal systems.

What is the classification of colloids on the basis of nature of interaction?

When the dispersion phase and dispersion medium interact then colloids are classified into lyophilic sols and lyophobic sols.
The dispersed phase particles have a great affinity for the dispersion medium in lyophilic sols, Which are reversible.
Examples are gum, gelatin, starch, proteins, etc.

What classifies a colloid?

colloid, any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye; more broadly, any substance, including thin films and fibres, having at least one dimension in this general size range, which encompasses about 10⁻⁷ to 10⁻³ cm.

Classification Of Colloids FAQs Aerosols, solid aerosols, foams, solid foams, emulsions, sols, solid sols, and gels are 8 types of colloids.
