Can paint have dispersed particles?
Yes, paint can have a dispersed particle because the paint is most of the time sol in which tiny solid particles are dispersed in a liquid medium.
Dispersed phase: The dispersed phase is a discontinuous phase that is spread throughout a colloidal solution.
Dispersion medium: The dispersion medium is a continuous medium that is present throughout the medium in which the dispersed phase is spread in a discontinuous fashion.
For example: In the case of paint the tiny paint particles are in the dispersed phase which is spread throughout the colloidal solution while the liquid medium is the dispersion medium in which paint particle is spread.
Sol: The liquid state of a colloidal solution is a sol. Sol is a heterogenous mixture having two-component a disperse phase and a dispersion medium.
Sol is of many types. For example,
Solid sol: A solid sol is a colloidal solution in which solid is a dispersed phase and solid is a dispersion medium too.
Example: Gems, alloys
Liquid sol: Liquid sol is a colloidal solution in which liquid is a dispersed phase and liquid is a dispersion medium too. It is also called an emulsion.
Example: milk
Aerosol: Aerosol is a colloidal solution in which solid is a dispersed phase and gas is a dispersion medium.
Example: smoke
