Question

Why do not the dispersed phase particles in a colloidal solution combine with one another?

Answer 1

• 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 dispersed phase particles in a colloidal solution do not combine with one another because of the presence of either a positive or negative charge on them. Due to mutual repulsion, these particles remain scattered in the colloidal solution.
