Origin of Charges on Colloidal Particles (COLLOIDS)...!

Origin Of Charges On Colloidal Particles (Colloids) As we know that in Colloids the Dispersed phase remains suspended in Dispersion medium. The Colloidal system is a two phase system and very stable. It does not grow in size or lead to precipitation. This remarkable stability of Colloids is due to the presence of a small quantity of electrolyte in the medium and presence of charge on the surface of colloids. The colloidal particles carry an electric charge on it either positive...

What are Colloids, their Properties and their Types..?

There are three major groups of mixtures,they are :- a) Solution :- ·        A solution is a homogeneous mixture of two or more components. ·        The dissolving agent is called as solvent where as the substance which is dissolved is called as solute. ·        The components of a solution are unevenly distributed and cannot be seperated. ·        The components of a solution...

Ideal Gas & Ideal Gas Law

What is an Ideal Gas ???? An Ideal Gas or a Perfect Gas is the one which is composed of a set of randomly-moving, non-interacting point particles. An Ideal Gas obeys Boyle's Law and Charle's Law. Practically ideal gas does not exist,But many common gases exhibit behaviour very close to that of an Ideal Gas at ambient temperature and pressure. Ideal Gas Law :- A law relating the pressure, temperature , and volume of an ideal gas is called as Ideal Gas Law . It was first stated by a Physicist and Engineer Benoit Paul Emile...
