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

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..

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..

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..

If we are given the number of persons, number of jobs and the expected productivity of a particular person on a particular job, linear programming is used to maximise the average productivity of a perso..

A solution obtained, by assigning particular values to the arbitrary constants in the general solution of the differential equation, is called its particular solution..

Solution is defined as a homogeneous mixture of two or more chemical substances. The state of matter of a solution may be solid, liquid or gaseous. For example, common salt in water (liquid solution), air (gaseous solution), alloys (solid solution),..

is a homogeneous mixture of a solute dissolved in a solvent. Examples: Salt and water, sugar and water, iodine and alcohol. It should be remembered that: 1. A Solution is a homogeneous mixture of two or more substances. These substances can be in any of the three physical stat..
