Which gas is added to drinks to make them fizzy?
Carbon die oxide Carbonated water, also known as sparkling water, fizzy water, seltzer, and water with gas, (collectively as an aerated beverage), 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 chemical formula H2CO3). Carbonated water, also known as soda water, can be produced in the home by “charging” a refillable seltzer bottle by filling it with water and then adding carbon dioxide. Club soda may be identical to plain carbonated water or it may contain a small amount of table salt, sodium citrate, sodium bicarbonate, potassium bicarbonate, potassium citrate, potassium sulfate, or disodium phosphate, depending on the bottler. These additives are included to emulate the slightly salty taste of homemade soda water. The process can also occur naturally to produce carbonated mineral

Carbon dioxide is colourless and flavourless. Carbonated Beverages have as their base either carbonated water or soda water – which are considered Carbonated Beverages in their own right. Usually flavour and sweetener are added. Such beverages are mostly water, 90% and up (diet ones can be 99% water.) Water often has a trace amount of carbon dioxide in it anyway, but carbonated water is water that has been super-saturated with it, to create the pleasant bubbly sensation. When carbon dioxide mixes with water, it forms carbonic acid: CO2 + H2O = H2CO3 It’s this acid that creates the tingling on your tongue. You can also make any drink you want a fizzy drink, such as juices, teas, or wines, by the addition of some carbonated water. Technically, a gin and tonic, and even beer count as a Carbonated Beverage, but most
