The types of Chemical weathering are: Dissolution: This occurs when rainfall is slightly acidic and gases in the air are added to it. This consequent mix can cause solution weathering of rocks. Hydration: Hydration is a form of chemical weathering that involves the rigid attachment of H+ and OH- ions to the atoms and molecules of a mineral. Hydrolysis: This is a chemical weathering process affecting Silicate minerals. is a chemical weathering process affecting Silicate minerals. In such reactions, pure water ionizes slightly and reacts with silicate minerals.
