How does weathering affect limestone? - Internet Geography

Aug 15, 2022Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

What is the reaction of limestone with water? - Frostburg State University

Limestone (CaCO 3) reacts with hydrogen ions in water. These are always present in water, since water undergoes autoprotolysis: H 2 O (l) = H + (aq) + OH - (aq) The more acidic the water is, the more limestone will react, and erode. The erosion of marble sculpture and inscriptions exposed to the elements is one of the consequences of acid rain.

An Explanation of How Limestone Caves are Formed at Every Stage

This is because rainwater absorbs carbon dioxide and thus becomes acidic. Rainwater therefore dissolves calcium carbonate and turns it into a calcium bicarbonate solution. The chemical formula for this reaction is: CaCO 3 (s) + H 2 O (l) + CO 2 (aq) → Ca (HCO 3) 2 (aq) (Different colors indicate, different parts of a lime rock)

In the new process, the pulverized limestone is dissolved in the acid at one electrode and high-purity carbon dioxide is released, while calcium hydroxide, generally known as lime, precipitates out as a solid at the other. The calcium hydroxide can then be processed in another step to produce the cement, which is mostly calcium silicate.
