Chemical Reaction

The process which leads to chemical change is called chemical reaction. Most of the chemical changes are irreversible in nature. However, some chemical changes can be reversed by chemical processes. Change in color, change in temperature, evolution of gas, formation of precipitate, etc. are signs of a chemical change. Chemical reactions are shown by chemical equations; which are written by using appropriate symbols of reactants and products. A chemical equation also shows information; like change in temperature, physical states of reactants and products, etc. A good understanding of chemical reactions is necessary to make a solid foundation of study of chemistry.
