Carbonation occurs when carbon dioxide Carbon dioxide is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state. CO2 is a trace gas being only 0.038% of the atmosphere is dissolved Solvation, also sometimes called dissolution, is the process of attraction and association of molecules of a solvent with molecules or ions of a solute. As ions dissolve in a solvent they spread out and become surrounded by solvent molecules in water Water is a ubiquitous chemical substance that is composed of hydrogen and oxygen and is essential for all known forms of life or an aqueous An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending to the relevant formula. The word aqueous means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent as well as naturally abundant, it is a ubiquitous solvent in chemistry solution In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is dissolved in another substance, known as a solvent. This process yields the "fizz" to carbonated water Carbonated water, also known as sparkling water, fizzy water, seltzer, and water with gas, , is plain water into which carbon dioxide gas has been dissolved, and is the major and defining component of most soft drinks. The process of dissolving carbon dioxide gas is called carbonation. It results in the formation of carbonic acid (which has the, sparkling mineral water Mineral water is water containing minerals or other dissolved substances that alter its taste or give it therapeutic value. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the water. Mineral water can often be effervescent. Mineral water can be prepared or can be obtained from naturally occurring mineral, and soft drinks A soft drink is a drink that does not contain alcohol. Soft drinks are often carbonated and commonly consumed while cold. The most common soft drinks are colas, flavored water, sparkling water, iced tea, sweet tea, lemonade, squash and fruit punch; the head The density and longevity of the head will be determined by the type of malt and adjunct from which the beer was fermented.

Effervescence
Effervescence is the escape of gas from an aqueous solution. The term is used to describe the foaming or fizzing that results from a release of gas. In the lab, a common example of effervescence is the addition of hydrochloric acid Hydrochloric acid is the solution of hydrogen chloride (H to a block of limestone Limestone is a sedimentary rock composed largely of the mineral calcite . The deposition of limestone strata is often a by-product and indicator of biological activity in the geologic record. Calcium (along with nitrogen, phosphorus, and potassium) is a key mineral to plant nutrition: soils overlying limestone bedrock tend to be pre-fertilized. If a few pieces of marble Marble is a non foliated metamorphic rock resulting from the metamorphism of limestone, composed mostly of calcite (a crystalline form of calcium carbonate, Ca or an antacid An antacid is any substance, generally a base or basic salt, which counteracts stomach acidity. In other words, antacids are stomach acid neutralizers tablet are put in hydrochloric acid in a test tube A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom. A large test tube designed specifically for boiling liquids is called a boiling tube fitted with a cork Cork material is an impermeable, buoyant material, a prime-subset of generic cork tissue that is harvested for commercial use primarily from Quercus suber that is endemic to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance, and because of its impermeability, buoyancy, elasticity, and fire resistance, it, effervescence of carbon dioxide Carbon dioxide is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state. CO2 is a trace gas being only 0.038% of the atmosphere can be witnessed.
The carbonic acid formed rapidly decomposes into water and carbon dioxide gas, thus the reaction becomes:
Another chemical reaction A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. They are studied by chemists under a field of science called chemistry. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, often coming about only after the input of some type of energy, viz that produces gas is the reaction of sodium bicarbonate with acid, for example in Alka-Seltzer brand tablets, used to treat stomach indigestion Dyspepsia (from the Greek "δυς-" and "πέψη" (Pepse)), popularly known as indigestion, meaning hard or difficult digestion, is a medical condition characterized by chronic or recurrent pain in the upper abdomen, upper abdominal fullness and feeling full earlier than expected when eating. It can be accompanied by bloating,. The essential chemical reaction is:
The process of carbon dioxide bubbling out of solution is generally represented by the following reaction A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. They are studied by chemists under a field of science called chemistry. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, often coming about only after the input of some type of energy, viz, where a pressurized dilute solution of carbonic acid Carbonic acid has 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 hydrogen carbonates) and carbonates. It is a weak acid. Carbonic acid should never be confused with carbolic acid, an antiquated name for in water releases gaseous carbon dioxide at decompression:
In simple terms, it is the result of the chemical reaction occurring in the liquid which produces a gaseous product.
Measuring carbonation
The quality of carbonated beverages including soft drinks, seltzer and beer is affected by the amount of dissolved CO2 (the gas that causes carbonation) and the amount of carbonic acid in the drink. Carbon dioxide (CO2) has an infrared absorption wavelength of 4.27 micrometers A micrometre or micron is one millionth of a metre, or equivalently one thousandth of a millimetre or one thousand nanometres. It can also be written in scientific notation as 1×10−6 m, meaning 1⁄1000000 m and can be measured online using an infrared carbonation sensor. This is an improvement to the traditional inferred measurement method using temperature and pressure for Henry's Law In chemistry, Henry's law is one of the gas laws, formulated by William Henry in 1803. It states that: coefficients In mathematics, a coefficient is a constant multiplicative factor of a specific object. For example, in the expression 9x2, the coefficient of x2 is 9 because this methodology is influenced by changes in density and alcohol content. Infrared measurements are not affected by changes in density or alcohol content because they are actually measuring the CO2 molecule using the Beer–Lambert law. The amount of carbonation in a beverage is measured in Volumes or grams/liter. This is because introducing CO2 into a beverage will change its weight. An easy experiment to prove this is to take a seltzer bottle and weigh it. Carefully remove the top slowly so no liquid escapes from the bottle as the gas escapes the weight of the bottle of seltzer will go down. Shaking the bottle while closed and then opening it to remove more CO2 will increase this effect.
Natural and forced carbonation
Natural carbonation is the build up of natural gasses during fermentation. Forced carbonation is when carbon dioxide is added to the substance under pressure.
Uses
In many consumer beverages such as soft drinks A soft drink is a drink that does not contain alcohol. Soft drinks are often carbonated and commonly consumed while cold. The most common soft drinks are colas, flavored water, sparkling water, iced tea, sweet tea, lemonade, squash and fruit punch, carbonation is used to give "bite." The fizzy taste can be caused by dilute carbonic acid Carbonic acid has 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 hydrogen carbonates) and carbonates. It is a weak acid. Carbonic acid should never be confused with carbolic acid, an antiquated name for inducing a slight burning sensation, but is never caused by the presence of bubbles. This can be shown by drinking a fizzy drink in a hyperbaric chamber The historically older open diving chamber is in effect a large diving bell, utilising the equivalent of a moon pool to equalise internal air pressure and external water pressure automatically without the need, necessarily, to measure and control it. An air compressor or bottled compressed air is required to maintain the volume of the air as it at the same pressure as the beverage. This can give much the same taste as at sea level. In any case, the bubbles will be completely absent during this experience. If you were to taste a flat soda at this pressure, you might experience a much different flavor profile as carbonic acid Carbonic acid has 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 hydrogen carbonates) and carbonates. It is a weak acid. Carbonic acid should never be confused with carbolic acid, an antiquated name for has a low vapor pressure, and the only "bite" would come from other acids in the soda. However, in the case of Pepsi Pepsi is a carbonated soft drink produced and manufactured by PepsiCo. The drink was first made in the 1890s by pharmacist Caleb Bradham in New Bern, North Carolina. The brand was trademarked on June 16, 1903. There have been many Pepsi variants produced over the years since 1898 and Coca-Cola Coca-Cola is a carbonated soft drink sold in stores, restaurants, and vending machines internationally. The Coca-Cola Company claims that the beverage is sold in more than 200 countries. It is produced by The Coca-Cola Company in Atlanta, Georgia, and is often referred to simply as Coke or (in European and American countries) as cola or pop, much of the perceived bite is due to phosphoric acid Phosphoric acid, also known as orthophosphoric acid or phosphoric acid, is a mineral (inorganic) acid having the chemical formula H3P , an acid not known for fizz or changes in flavor profile due to changes in pressure.
Carbonation is sometimes used for reasons other than taste. For example, carbonation reduces the availability of free oxygen in a soda, and it can reduce the pH pH is a measure of the acidity or basicity of a solution. It is defined as the cologarithm of the activity of dissolved hydrogen ions . Hydrogen ion activity coefficients cannot be measured experimentally, so they are based on theoretical calculations. The pH scale is not an absolute scale; it is relative to a set of standard solutions whose pH is of a liquid by a small amount. Some carpet cleaning Carpet cleaning, for beautification, and removal of stains, dirt, grit, sand, and allergens, is achieved by several methods, both traditional and modern. Clean carpets are recognized by manufacturers as being more visually pleasing, potentially longer-lasting and probably healthier than poorly maintained carpets solutions are carbonated in order to more effectively dissolve organic material.[citation needed]
Brewing
In homebrewing Homebrewing is the brewing of beer, wine, cider and other beverages, both alcoholic and non-alcoholic, through fermentation on a small scale as a hobby for personal consumption, free distribution at social gatherings, amateur brewing competitions or other non-commercial reasons, overcarbonation can be dangerous; it can result in bottles gushing or even exploding. Adding priming sugar or malt Malting is a process applied to cereal grains, in which the grains are made to germinate by soaking in water and are then quickly halted from germinating further by drying/heating with hot air. Thus, malting is a combination of two processes: the sprouting process and the kiln-drying process. These latter terms are often preferred when referring extract at bottling time to beer that has had its fermentable sugar content totally consumed is the safest approach to carbonation. Exceeding recommended levels of priming sugar for a given recipe is dangerous, as is using inappropriate bottles or improper capping methods. Beer may also be force-carbonated using a keg and special bottling equipment so that the carbonation level can be carefully controlled.
