Chemical Weathering

Oct 04, 2021Chemical 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.

The Formation of Stalactites and Stalagmites

H 2 0 + CO 2 + CaCO 3 = Ca (HCO 3) 2. Ca (HCO 3) 2 is known as calcium bicarbonate, and the water carries the substance, basically dissolved calcite, through the cracks of the roof of a cave.Once water comes into contact with the air inside the cave, however, some of the calcium bicarbonate is transformed back into calcium carbonate, and calcite starts to form around the crack.

Carbonate Rocks. The carbonate rocks make up 10 to 15% of sedimentary rocks. They largely consist of two types of rocks. Limestones which are composed mostly of calcite (CaCO 3) or high Mg calcite [(Ca,Mg)CO 3], and . Dolostones which are composed mostly of dolomite [CaMg(CO 3) 2].

This process is reversible up to a certain stress threshold, but it is still a dissipative, nonelastic process [Bowden and Cooper, 1962]. It is therefore likely that there are stress-dependent, intermittent, dissipative processes

Water softening process overview

Water softening is a process in which the ions of calcium, magnesium and sometimes iron are removed. It is these ions in hard water that make it difficult for products with other positively charged ions to dissolve in the water. By doing this, the water softening removes the offending minerals from the water.
