How are the following colloids different from each other in respect of
dispersion medium and dispersed phase? Give one example of each type.
(i) An aerosol (ii) A hydrosol (iii) An emulsion
(i) An aerosol: It is a colloidal solution in which dispersed phase is a
solid and dispersion medium is a gas.
Example: Smoke, haze.
(ii) A hydrosol: The colloidal solution where water is used as the dispersion
medium is called hydrosol or aquasol.
Example: Starch sol.
(iii) An emulsion: The colloidal solution in which both dispersed phase and
medium are in liquid state.
Example: Milk, cream.
