Preparation of Colloidal Sols
Preparation of Colloidal Sols - For the preparation of lyophilic and lyophobic sols different methods are us..
Purification of Colloidal Sols
Purification of Colloidal Sols - The colloidal solutions prepared by various methods usually contain electrolytes and other soluble substances as impurities. These impurities if not removed can destabilize the sols. Impurities are removed by the following methods: 1) D..

Properties of Colloidal Sols
Heterogenous nature - Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..
Preparation of Colloidal Sols
Preparation of Lyophilic Sols Since lyophilic sols are quite stable, they can be easily prepared by shaking the lyophilic substance with the dispersion medium. Examples are: Colloidal sols of gum, starch, gelatine and egg albumi..

Great tutor! Was both helpful and responsive to questions! Did not just want to give me an answer, but took the time to explain any steps I did not understand! - Robert
Really helpful and explained things very clearly! Even though my session got over I can complete my homework myself
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
