Question
What is the reason fo the stability of colloidal sols ?
Solution
In colloidal sols, the colloidal particles carry a particular charge and the dispersion medium carries an equal but opposite charge. Due to the presence of these similar and equal charges, the particles of the colloid sol repel one another and cannot combine together to form larger particles which keep them dispersed in the medium and the colloidal remains stable.
