Carbonated+water

The bubbles that are in carbonated water are made from carbon dioxide. Carbon dioxide is dissolved in water at a low concentration. Carbonated water has a PH of around 3 and 4 thus having a slightly sour taste. **Carbonated water** (also known as **club soda**, **soda water**, **sparkling water**,**seltzer**, or **fizzy water**) is [|water] into which [|carbon dioxide] gas under pressure has been dissolved, a process that causes the water to become [|effervescent]. Carbonated water is the defining ingredient of [|carbonated soft drinks]. The process of dissolving carbon dioxide in water is called [|carbonation].

__**History**__ In 1767 [|Joseph Priestley] invented carbonated water when he first discovered a method of infusing water with carbon dioxide when he suspended a bowl of water above a beer vat at a local brewery in [|Leeds], England. [|[8]] 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 offered it to friends as a cool, refreshing drink. In 1772, Priestley published a paper entitled "Impregnating Water with Fixed Air" in which he describes dripping "oil of vitriol" ( [|sulfuric acid] ) onto [|chalk] to produce carbon dioxide gas, and encouraging the gas to dissolve into an agitated bowl of water. __** Soda Siphon **__ This contraption can be used to make carbonated soda from your household. It has a CO2, and with all the gas pressure it is able to pressurize the water thus creating carbonated water.
