A Wisdom Archive on carbonic acid

Carbonic acid has two acidic hydrogens and so two dissociation constants: H2CO3 ⇌ HCO3− + H+ Ka1 = 2.5×10−4 mol/L; pKa1 = 3.60. HCO3− ⇌ CO32− + H+ Ka2 = 5.61×10−11 mol/L; p ...

Carbonic acid is a carbon-containing acid with the formula H2CO3. It is also a name sometimes given to solutions of carbon dioxide in water, which contain small amounts of H2CO3. The salts of carbonic acids are called bicarbonates (or hydrogencarbonates) and carbonates. Carbon dioxide dissolved in water is in equilibrium with carbonic acid: CO2 + H2 ... Including:

This refers to the bicarbonate ion, for baking soda, see Sodium bicarbonate. A Bicarbonate or, more properly, a hydrogen carbonate is a polyatomic ion whose formula is HCO3-. It is the intermediate form in the deprotonation of carbonic acid: removing the first proton from carbonic acid forms bicarbonate; removing the second proton leads to the carbonate ion. The salts which contain the bicarbonate ion are also known as bicarbonates, such as sodium bicarbonate (baking soda) NaHCO ...

Saturated fat is fat that consists of triglycerides containing only saturated fatty acids. Saturated fatty acids have no double bonds between the carbon atoms of the fatty acid chain (hence, they are fully saturated with hydrogen atoms). There are several kinds of naturally occurring saturated fatty acids, with their only difference being the number of carbon atoms - from 1 to 24. Some common examples of saturated fatty acids are butyric acid with 4 carbon atoms (contained in butter), lauric acid with 12 carbon atoms (contained in mot ... Including:

Carbonate is an anion with a charge of -2 and an empirical formula of CO32-. For an aqueous solution, carbonate exists in three forms. In strongly basic conditions, the carbonate ion, CO32-, predominates. In weakly basic conditions, bicarbonate ion, HCO3- is prevalent. In acid conditions, aqueous carbon dioxide, CO2(aq), is the main form. This also contains a minute amount of carbonic acid, H2CO3. Thus sodium carbonate is basic, sodium bicarbonate is weakly ba ...

Weathering is the process of decomposition and/or disintegration of rocks, soils and their minerals through natural, chemical, and biological processes that is, in place. It is not to be confused with erosion, which is the movement of rocks and/or weathering products by water, wind, ice or gravity. The breakdown products, after chemical weathering of rock and sediment minerals and the leaching out of the more soluble parts, when combined with decaying organic material, is called soil. The mineral content of the soil is determin ... Including:

Carbonation occurs when carbon dioxide is dissolved in water or an aqueous solution. This process is generally represented by the following reaction, where water and gaseous carbon dioxide react to form a dilute solution of carbonic acid. H2O + CO2 ↔ H2CO3 This process yields the "fizz" to carbonated water and sparkling mineral water, the head to beer, and the cor ...

Acid rain is defined as any type of precipitation with a pH of below 5.0. Normal rain has a pH which can range between 4.5 and 5.6 with an average value of 5.0. This natural acidity is caused by dissolved carbon dioxide dissociating to form weak carbonic acid. 'Acid rain' is caused by sulfur from volcanic venting or impurities in fossil fuels, and nitrogen from the air, combining with oxygen to form sulfur dioxide and nitrogen oxides. These diffuse into the atmosphere and react with water to form sulfuric and nitric acids which are so ... Including:

Carbonated water, also known as soda water, sparkling water, or seltzer water, is plain water into which carbon dioxide gas has been dissolved. The process of dissolving carbon dioxide gas is called carbonation. It results in the formation of carbonic acid (which has the chemical formula H2CO3). Club soda may be identical to plain carbonated water or it may contain a small amount table salt, sodium citrate, sodium bicarbonate, potassium bicarbonate, potassium s ...
