Other sparkling wines, such as prosecco, are fermented using force-carbonation — a faster process that involves using machinery to manually add CO 2 and create bubbles. [5] Sweet wines or off-dry wines are made by arresting fermentation before all sugar has been converted into ethanol and allowing some residual sugar to remain. This can be ...
Carbonation of ammonia is one step in the industrial production of urea:In 2020, worldwide production capacity was approximately 180 million tonnes. [3] As a fertilizer, it is a source of nitrogen for plants. Urea production plants are almost always located adjacent to the site where the ammonia is manufactured. [4] 2 NH 3 + CO 2 ⇌ [NH 4 ...
Carbonatation is a slow process that occurs in concrete where lime (CaO, or Ca(OH) 2 ) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium carbonate. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5.
Beer may also be force-carbonated using a keg and special bottling equipment so that the carbonation level can be carefully controlled. Carbonation is often achieved with approximately 4 ounces (110 g) of corn sugar boiled in 2 cups (500 mL) of water then cooled and added to a typical 5-US-gallon (19 L) batch before bottling. [71]
A series of processes that involve carbonization. [2]Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization.
Soda makers or soda carbonators are appliances that carbonate water with multiple-use carbon dioxide canisters. A variety of systems are produced by manufacturers and hobbyists. [42] [43] The commercial units may be sold with concentrated syrup for making flavored soft drinks. One major producer of soda carbonators is SodaStream. Their products ...
Carboxylation is a chemical reaction in which a carboxylic acid is produced by treating a substrate with carbon dioxide. [1] The opposite reaction is decarboxylation.In chemistry, the term carbonation is sometimes used synonymously with carboxylation, especially when applied to the reaction of carbanionic reagents with CO 2.
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
