Interpretation: The two circumstances that help keep colloidal particles in suspension need to be explained.
Concept Introduction: A colloidal dispersion is made up of solid, liquid, or gas particles in a dispersed phase. Colloidal particles range in size from 1 nm to
Explanation of Solution
Suspension is a heterogeneous mixture where solid particles are spread throughout the liquid without dissolving. The circumstances due to which colloidal particles are in suspension are Brownian motion and the repulsion of charges on the surfaces of the colloidal particles. These charges are absorbed on its surface. Here, Brownian motion is defined as the random motion of a particle that causes interaction between ions.
