In 1767 Priestley discovered a method of infusing water with carbon dioxide by pouring water back and forth above a beer vat at a local brewery in Leeds, England. [30] [31] [32] The air blanketing the fermenting beer—called 'fixed air'—was known to kill mice suspended in it. Priestley found water thus treated had a pleasant taste, and he ...
‡ Second column of table indicates solubility at each given temperature in volume of CO 2 as it would be measured at 101.3 kPa and 0 °C per volume of water. The solubility is given for "pure water", i.e., water which contain only CO 2. This water is going to be acidic. For example, at 25 °C the pH of 3.9 is expected (see carbonic acid).
Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2 ), which cannot occur under atmospheric pressure. It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point ) and above −56.6 °C (−69.9 °F) (temperature of triple point ). [ 1 ]
The taste of soda water (and related taste sensations in other carbonated beverages) is an effect of the dissolved carbon dioxide rather than the bursting bubbles of the gas. Carbonic anhydrase 4 converts carbon dioxide to carbonic acid leading to a sour taste, and also the dissolved carbon dioxide induces a somatosensory response.
The soda is referred to as "premix" in the industry, as compared to "postmix" bag-in-box (BiB) packages which are concentrated syrup. BiB soda is cheaper but requires a high-quality water source and well-calibrated dispenser. Premix soda costs more and takes up more space, but can be used anywhere, and the equipment is simpler and cheaper.
A private-label-brand club soda as seen in Canada. Club soda is a form of carbonated water manufactured in North America, commonly used as a drink mixer. Sodium bicarbonate, potassium sulfate, potassium bicarbonate, potassium citrate, or sodium citrate is added to artificially replicate constituents commonly found in natural mineral waters [1] and offset the acidity of introducing carbon ...

If natural mineral water is effervescent, it must be labelled accordingly, depending on the origin of the carbon dioxide: naturally carbonated natural mineral water (no introduction of CO 2); natural mineral water fortified with gas from the spring (reintroduction of CO 2); carbonated natural mineral water (CO 2 added following strict guidelines).
