Question

Colloidal solutions can be prepared in water and in air as media. What distinctive names are given to these two types of sols?

Answer 1

Colloidal solutions prepared in different dispersion media are given distinctive names based on the medium used. When the dispersion medium is water, the colloidal solution is called a hydrosol. Conversely, when air is the dispersion medium, the colloidal solution is called an aerosol. Thus, sols with water as the dispersion medium are termed hydrosols, and those dispersed in air are termed aerosols. This terminology highlights the nature of the medium in which the solid particles are dispersed to form the colloidal solution.
