When calcium carbonate (CaCO3) is reacted with

Jan 20, 2011Best Answer: The reaction of acid (in this case HCl) and a carbonate (in this case CaCO3) always produces a gas. The molecular equation nominally looks as follows: 2 HCl + CaCO3 -- CaCl2 + H2CO3. H2CO3, carbonic acid, is a weak acid that is unstable in water solutions at high concentrations.

List of Carbonic anhydrase inhibitors

Carbonic anhydrase inhibitors reduce the activity of carbonic anhydrase, an enzyme responsible for catalyzing the reaction between carbon dioxide and water into carbonic acid and then bicarbonate. This reduces the resorption of bicarbonate from the proximal tubule in the kidneys, which causes a direct increase in bicarbonate excretion and mild increases in sodium, and potassium excretion.

Structure and mechanism of carbonic anhydrase.

Carbonic anhydrase (CA; carbonate hydro-lyase, EC 4.2.1.1) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O--HCO3 (-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.

What is the reaction of carbonic acid?

CO2 gas is a Lewis acid in that it accepts electrons from Lewis bases (electron donors). When dissolved in water a reaction takes place between the Lewis donor (water) and the CO2 which gives rise to carbonic acid which is a different substance to CO2 and has the formula (H2CO3).

Carbonic anhydrase

The carbonic anhydrases form a family of enzymes that catalyze the interconversion between carbon dioxide and water and the dissociated ions of carbonic acid. The active site of most carbonic anhydrases contains a zinc ion. They are therefore classified as metalloenzymes. The enzyme maintains acid-base balance and helps transport carbon dioxide. Carbonic anhydrase helps regulate pH and fluid balance.
