The three important agents which are involved in chemical weathering are –water,, carbon dioxide and oxygen. Among the three most important chemical weathering agent is water. With a simple formula H2O, the two hydrogen atoms bonded to one oxygen atom. This structure of water gives it a polar molecule property due to which it can polarize itself into negative and positive poles. The hydrogen is the positive pole with (+1) charge while the oxygen is the negative pole with (-2) charge and they attract ions opposite to their charge numbers.This exerts a molecular force on the surrounding molecules and they dissociate to get polarized and form new molecule. This process is called hydrolysis where a mineral is dissolved in water and ions from the minerals are carried away. These elements undergo the process of leaching.
