Femtochemistry is the area in the field of physical chemistry that deals with studying of the chemical reactions on a minute time scale (one femtosecond or 10-15 seconds). This is done to study the action of atoms within the molecules to form new molecules by rearranging themselves.
In the field of chemistry, Le Chatelier’s principle is also known as the Equilibrium Law. It is helpful in predicting the effect of a change in conditions on the chemical equilibrium. This principle was named after Henry Louis Le Chatelier and Karl Ferdinand Braun.
Water has the ability to dissolve a large number of substances, e.g. sugar, salts etc. Water also dissolves a large number of gases including ammonia, hydrogen chloride etc. Hence, water dissolves almost every common substance and is therefore called a ‘universal solvent’.
