Give one example of the colloidal solution in which solid acts as the dispersed phase and gas as the dispersion medium.
Colloidal solution: It is a mixture in which one substance of which particles are insoluble and microscopically suspended throughout the other substance. It seems to be a homogeneous mixture but in actuality, it is heterogeneous in nature. It has two components one is the substance that is suspended in the mixture and is known as the dispersed phase and the other component is the dispersing medium into which the dispersed phase is suspended.
The dust storm is the colloidal solution in which dust particles are solid acting as the dispersed phase and the air is the dispersion medium.
