Electrochemistry Total views (0)  
Substances which allow the flow of current through them are called electrical conductors. Conductors are broadly classified into two types. 1. Metallic conductors or electronic conductors. 2. Electrolytic conductors. Metallic conductors conduct electricity due to the movement of free electrons from a higher negative potential to a lower one without producing any chemical change.

Determinati on of hydrolysis constant: Molar conductance of an aqueous solution of a salt of strong acid and weak base like aniline hydrochloride is partly due to HCl formed as a result of hydrolysis and partly due to unhydrolysed salt.

Additive property is one which for a system is the sum of two corresponding properties of the constituents. The strictly additive property is mass. Mass of molecule is the sum of the masses of the atoms. The mass of mixture is sum of the separate masses of the constituent parts. By adding atomic weights of constituent atoms molecular weight of a molecule is obtained. This property is possesse ......

Chemical Spectroscopy Total views (0)  
Molecular spectroscopy may be defined as the study of interaction of electromagnetic radiation with matter. With the help of spectroscopy, structure of the compound can be derived. Electromagnetic radiation consists of various light radiations with varying energies. Visible light is a small portion of electromagnetic radiation.

Ordinary reactions are initiated by activation due to molecular collisions. The average kinetic energy of translational motion (4.184 kJmol-1) is not sufficient to brought about chemical transformation, which requires about 40 - 60 kJmol-1 of energy. Another way to provide activation is to bring the molecule to collide with photons of UV light, X-rays, or γ-rays. Thus photochemistry deals ......
