Example: Calcium sulfate reacts with water to form gypsum. CaSO₄ + 2H₂O → Gypsum Another example is the formation of Limonite. Fe₂O₃ + 3H₂O → Fe₂O₃·3H₂O Limonite usually shows a yellowish color and is common in lateritic soils. 2. Hydrolysis Hydrolysis is one of the most important processes …

Hydrolysis Hydrolysis is one of the most important processes of chemical weathering in soil formation. In this process, water molecules split into hydrogen and hydroxyl ions. H₂O → H⁺ + OH⁻ The hydrogen ions react with minerals, causing chemical changes and f
