Chemical weathering can also result from exposure to water. Hydrolysis occurs when silicate minerals react with water so that the mineral recombines with the water molecule to form a new mineral.For example, consider the mineral potassium feldspar.hemical weathering refers to the processes by which rocks react with the atmosphere to form new substances. These reactions can alter a rock and transform the rock into sand, clays, and other minerals.
