Weathering and Soils: Weathering

Hydrolysis is a kind of chemical weathering that takes place when water reacts with silicate minerals in soils and rocks. In a hydrolysis reaction, the silicate minerals are broken down or weakened. This picture shows the mineral, kaolinite, a soft clay mineral that is formed when the harder mineral, orthoclase, undergoes hydrolysis.

Chemical Weathering | Processes of Change

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. Potassium feldspar is a fairly common mineral and can be found in igneous, metamorphic and sedimentary rocks.

Hydrolysis takes place when acid rain reacts with rock-forming minerals such as feldspar to produce clay and salts that are removed in solution. The only common rock-forming mineral that is not affected is quartz, which is a chemically resistant mineral. This is why quartz and clay are the two of the most common minerals in sedimentary rocks.

Chemical Weathering Explained - ThoughtCo

Chemical weathering does not break rocks into smaller fragments through wind, water and ice (that's physical weathering). Nor does it break rocks apart through the action of plants or animals (that's biological weathering). Instead, it changes the chemical composition of the rock, usually through carbonation, hydration, hydrolysis or oxidation.
