A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. While going under chemical reaction a substance is changed into one or more substances. It introduces the concept of electron exchange. A reaction can be an exothermic reaction or endothermic reaction. The substances involved in chemical reaction are called reactants and reagents.
Majority of the chemical reactions are usually performed in the solutions. Solvents play a vital role in occurrence of chemical reactions. It solvent’s both the reagent and the reactant so that they can dissolve. Solvents act as a mode of controlling the temperature in exothermic and endothermic reactions. In exothermic reactions, they provide a control over excess heat produced during the reaction by absorbing it. It is important to select the most appropriate solvent so as to get most effective results. A good solvent should be able to meet all the necessary standards such as it should be an inert to all the reaction conditions, the boiling point of the solvent should be appropriate, at the end of the reaction, there should not be any difficulty in its removal, it should dissolve the reagents and reactants.
