The highest order derivative of the unknown function occuring in the differential equation is the ________ of the differential equation => Power or Order or Degree or Particular solution or General solution..

Preparation of Colloidal Sols - For the preparation of lyophilic and lyophobic sols different methods are us..

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 album..

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..

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..
