solution containing charged particles

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 medium...

The e/m ratio of the anode rays obtained from hydrogen gas was found to be highest and equivalent to 9.58 x 10 4 C g - 1 . These particles carried a charge of 1.602 x 10 - 1 9 C. Thus, the mass of the positive particle from hydrogen gas is,..

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 met..

The proton is equal and opposite to the charge of an electron. So the absolute charge of a proton is 1.6 x 10 - 1 9 coulomb of positive charge. This being the smallest positive charge carried by any particle, it is taken as 1 unit positive ..

Smaller the size of the particles greater is the solubility. For example, it is easier to dissolve powdered sugar than granules of sug..

Why colloidal particles get charged? There are various reasons: i) Due to friction between the colloidal particles and molecules of dispersion medium, the colloidal particles become charged. ii) Charges on colloids appear due to preferenti..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons. As the protons are positively..

They get deflected by electric and magnetic fields. The deflection is large since a beta particle is lighter than an a -particle. They affect photographic plates. They ionise the gas through which they pass. The mass is 9.1 x 10 - 3 1 kg and its charge i..

An electron is found to carry 1.6 x 10 -19 coulomb of negative charge. This is the smallest negative charge known to be carried by any particle, and is consequently taken as the unit negative charge. The relative charge of a electron is -1 (minus on..
