Formally, a carbanion is the conjugate base of a carbon acid: R 3 CH + B − → R 3 C − + HB. where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp 3 carbon), alkenes (at an sp 2 carbon), arenes (at an sp 2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl , aryl, and alkynyl anions ...
Intravenous sodium bicarbonate is indicated in the treatment of metabolic acidosis, such as can occur in severe kidney disease, diabetic ketoacidosis [citation needed], circulatory insufficiency, extracorporeal circulation of blood, in hemolysis requiring alkalinization of the urine to avoid nephrotoxicity of blood pigments, and certain drug intoxications, such as by barbiturate overdose ...
The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3), bicarbonate ion (HCO − 3), and carbon dioxide (CO 2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function. [1] Catalyzed by carbonic anhydrase, carbon dioxide (CO 2 ...
Carbonic acid is a chemical compound with the chemical formula H 2 C O 3. The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature .
It is isoelectronic with nitric acid HNO 3. The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 ...
Carbonic anhydrase inhibitors are a class of pharmaceuticals that suppress the activity of carbonic anhydrase. Their clinical use has been established as anti- glaucoma agents, diuretics , antiepileptics , in the management of mountain sickness , gastric and duodenal ulcers , idiopathic intracranial hypertension , neurological disorders , or ...
Since carbon dioxide is in equilibrium with carbonic acid in the blood, hypercapnia drives serum pH down, resulting in respiratory acidosis. Clinically, the effect of hypercapnia on pH is estimated using the ratio of the arterial pressure of carbon dioxide to the concentration of bicarbonate ion, P a C O 2 / H C O 3 − {\displaystyle {P_{a_{CO ...
The anhydrides of some of these acids are oxides of carbon; carbon dioxide, for instance, can be seen as the anhydride of carbonic acid. Some important carbonates are Ag 2 CO 3, BaCO 3, CaCO 3, CdCO 3, Ce 2 (CO 3) 3, CoCO 3, Cs 2 CO 3, CuCO 3, FeCO 3, K 2 CO 3, La 2 (CO 3) 3, Li 2 CO 3, MgCO 3, MnCO 3, (NH 4) 2 CO 3, Na 2 CO 3, NiCO 3, PbCO 3 ...
