References The chemical formula for the acid is H2CO3 with a molecular weight 62.03 g/mol approximately. The water continues its downward course through narrow joints and fractures in the unsaturated zone with little further chemical reaction. The natural conversion of carbon dioxide to carbonic acid is a relatively slow process; however, carbonic anhydrase, a protein enzyme present inside the red blood cell, catalyzes this reaction with sufficient rapidity that it is accomplished in only a fraction of a second. pH of Carbonic Acid. It exists only in the form of its salts (carbonates), acid salts (hydrogen carbonates), amines (carbamic acid), and acid chlorides (carbonyl chloride). (From Grant and Hackh's Chemical Dictionary, 5th ed) Synonyms. carbonic acid reaction formula equilibrium constant (2a) true: H 2 CO 3 = H + + HCO 3-K true (2b) composite (apparent) H 2 CO 3 * = H + + HCO 3-K 1: The link between the reaction formula and the equilibrium constant is established by the law of mass action. Carbonic acid would actually be in the form of a triangular planar, where the three oxygen are 120 degrees apart from each other around the carbon. When the name of the anion ends in -ite, you drop the -ite, replace it with -ous, and add the word "acid." The element carbonate is the non-metal polyatomic ion. The subscript 3 represents how many atoms are directly bonded to the central atom. Carbonic acid derives from CO2 with the formula of H2CO3, while sulfuric acid is H2SO4. Carbonic acid ester halides, with the formula R–O–C(O)–X where R is an alkyl or aryl group and X is F, Cl, Br, or I can react easily with various compounds containing active hydrogens. 10 mM. Carbonic acid (H 2 CO 3) is formed in small amounts when its anhydride, carbon dioxide (CO 2), dissolves in water. Only 26 percent of the total carbon dioxide content of blood exists as bicarbonate inside the red blood cell, while 62 percent exists as bicarbonate in plasma; however, the bulk of bicarbonate ions is first produced inside the cell, then transported to the plasma. They are therefore classified as metalloenzymes.The enzyme maintains acid-base balance and helps … It is also known as respiratory acid or volatile acid as it is the only acid excreted as a gas by the lungs. Carbonic acid and carbonate salts. Carbonic acid can be considered to be a… Carbonic acid is a weak acid with chemical formula H 2 CO 3.

Carbonic acid ester halides, with the formula R–O–C(O)–X where R is an alkyl or aryl group and X is F, Cl, Br, or I can react easily with various compounds containing active hydrogens. Carbonated beverages contain an acidic molecule called carbonic acid that decomposes when you open a bottle or can of a fizzy drink. The simultaneous exchange of these two ions, known as the chloride shift, permits the plasma to be used as a storage site for bicarbonate without changing the electrical charge of either the plasma or the red blood cell. The active site of most carbonic anhydrases contains a zinc ion. The chemical structure of carbonic acid is shown below, and it consists of a carboxyl group, and two hydroxyl groups. Because the enzyme is present only inside the red blood cell, bicarbonate accumulates to a much greater extent within the red cell than in the plasma. Chemical formula: H 2 CO 3. In an open system, the partial pressure of CO 2 (g) is relatively constant at P(CO 2) = 0.000355 Atmosphere.

For example, at a pH of less than 8, the principal reactions and their relative speed are as follows: CO2 + H2O ⇌ H2CO3 (slow) H2CO3 + OH− ⇌ HCO3− + H2O (fast) Above pH 10 the following reactions are important: CO2 + OH− ⇌ HCO3− (slow) HCO3− + OH− ⇌ CO32− + H2O (fast) Between pH values of 8 and 10, all the above equilibrium reactions are significant. Carbonic acid definition, the acid, H2CO3, formed when carbon dioxide dissolves in water, known in the form of its salts and esters, the carbonates. Solutions of carbonic acid and carbon dioxide react with alkaline bases, forming carbonate salts. Calconcarbonic acid. Although differing in substrate specificity, subcellular localization, and tissue distribution, all isozymes of this family convert free long-chain fatty acids into fatty acyl-CoA esters, and thereby play a key role in lipid biosynthesis and fatty acid degradation. Carbonic acid can be considered to be a diprotic acid from which two series of salts can be formed—namely, hydrogen carbonates, containing HCO3−, and carbonates, containing CO32−.
