Which of the following represents the process of chemical weathering?

Solution (By Examveda Team)

Hydration and Hydrolysis represents the process of chemical weathering. In Hydration, Chemical combination of water molecules with a particular substance or mineral leading to a change in structure. In Hydrolysis, Most important process in chemical weathering. It is due to the dissociation of H₂O into H+ and OH- ions which chemically combine with minerals and bring about changes, such as exchange, decomposition of crystalline structure and formation of new compounds. Water acts as a weak acid on silicate minerals.
