Electrode Potential:- The electrical potential difference set up between metals and its ions in the solution is called electrode potential. Cell potential or EMF of a cell:- The difference between the electrode potential of the two half-cell is known as cell …
Polymer is simply high molecular mass macromolecules which consist of repeating structural units. The repeating structural units are called as monomers. The process of formation of polymers from respective monomers is called polymerization. Polymers are various types they are Polymer …
Surface chemistry is a branch of chemistry which deals the phenomenon of occurring at the interface of two phases. The interface between two phases is represented by hyphen or slash. Example: between solid and liquid represented by solid/liquid. There is …
A colloidal is a heterogeneous system in which one substance is dispersed (dispersed phase) as very fine particles into another substance called dispersion medium. Colloidal particles are larger than simple molecules but smaller enough to remains suspended their range of diameter …
a)Chemical method: – Colloidal solution can be prepared by chemical reaction leading to formation of molecules by double decomposition, oxidation, reduction or hydrolysis. These molecules then aggregate leading to form sols. b)Electrical disintegration or Bredig’s Arc Method: – Here Dispersion …
The process used for reducing the amount of impurities to a requisite minimum is known as purification of colloidal solution and it is carried out by following methods (I) Dialysis: – It is a process of removing a dissolved substance from a …
(I) Colligative Properties: – The values of colligative properties (osmotic pressure, lowering in vapor pressure, depression in freezing point, elevation in boiling point) are of small order as compared to values shown by true solution at same concentration. (II) Tyndall effect: – …
