What is Carbonic Acid

What is Carbonic AcidRole of carbonic acid in blood 

Carbonic acid is an advanced step in the transport of CO2 out of our bodies via respiratory gas exchange. The hydration reaction of CO2 is usually very slow in the lack of a catalyst, however red blood cells include carbonic anhydrase, which both raises the reaction rate and dissociates a hydrogen ion (H+) through the resulting carbonic acid, leaving bicarbonate (HCO3-) mixed in the blood plasma. 

Dissociation of Carbonic Acid 

Carbonic acid (H2CO3) is created in small sums when its anhydride, carbon dioxide (CO2), dissolves in water.CO2 + H2O ⇌ H2CO3 

The predominant species are merely loosely hydrated CO2 molecules. Carbonic acid could be considered to be a diprotic acid through which two series of salts can created, namely, carbonates, that contains CO32- and hydrogen carbonates, made up of HCO3-. 

H2CO3 + H2O ⇌ H3O+ + HCO3 HCO3 + H2O ⇌ H3O+ + CO32− 

However, the acid base behaviour of carbonic acid depends upon the various rates of some of the reactions involved, as well as their dependence on the pH of the system. For instance, at a pH of lower than 8, the principal reactions and their relative pace are as follows:

CO2 + H2O ⇌ H2CO3 (slow) H2CO3 + OH ⇌ HCO3 + H2O (fast)

How is Carbonic Acid Formed

Carbonic acid is formed when carbon dioxide within the air combines with rainwater. Throughout chemical weathering, the carbonic acid will behave with calcium carbonate based rocks, mostly chalk and limestone this is referred to as carbonation. However these rocks do not contain orthoclase feldspar or potassium feldspar as it is known.

Granite for instance does and when the weak carbonic acid (rainfall) weathers the stone, the feldspar will respond slowly over the years and will start to weaken this is known as kaolinization as the feldspar breaks down into kaolinite, which is a clay such as substance.
