CO2 is used for flavor, because it's cheap, and because it comes out of solution easily in nicely sized bubbles. When it comes to carbonating drinks, not all gasses will produce the same type or levels of fizziness, due to their different solubilities. Think of the difference between the bubbles in a bottle of seltzer water and a Guinness draft. That huge difference is almost solely due to differences in the gas used: pure CO2 for seltzer, ~70% N2/30%CO2 for Guinness. Similarly, N2O is used for whipped cream because it's lipid-soluble, anti-microbial, and has a slightly sweet taste.

Soft drinks contain dissolved carbon dioxide to give them their characteristic fizz or carbonation. The carbon dioxide is added under pressure, and when the bottle or can is opened, the pressure is released, causing the carbon dioxide to escape as bubbles, creating the carbonation in the drink.

Why do soft drinks fizz?

Soft drinks are also known as carbonated drinks. Have you thought why? Soft drinks contain chuge quantities of carbon dioxide under high pressure. The high pressure causes the gas to remain in dissolved state. Hence, when you open the bottle, the pressure falls, and the dissolved carbon dioxide can no longer remain dissolved, and hence escapes off, as fizzing.

What causes the fizzing in coca cola drinks?

The carbon dioxide which is dissolved in all fizzy drinks.


What does cola have in it?

Cola drinks contain carbonic acid (dissolved carbon dioxide gas) and many also contain phosphoric acid (and/or lactic acid) to balance the sweet taste.


What are the acid amounts in coke?

All soft drinks generally have carbonic acid (carbon dioxide dissolved in water under pressure). Some soft drinks also contain phosphoric acid.


Is nitrogen in fizzy drinks?

Yes, nitrogen is sometimes used to carbonate fizzy drinks instead of carbon dioxide. Nitrogen gives the drink a smoother mouthfeel and different carbonation characteristics compared to carbon dioxide.


What chemical gives soft drink it's bubbles?

Is the carbon dioxide of carbonated soft drinks organic or inorganic?

The carbon dioxide in carbonated soft drinks is considered inorganic because it does not contain carbon-hydrogen bonds typically found in organic compounds.


Why is carbonic acid preferred to other acids in fizzy drinks?

Carbonic acid is preferred in fizzy drinks because it is formed when carbon dioxide dissolves in water, giving the drinks their characteristic fizziness without imparting a strong acidic taste. It is a weak acid, so it does not overpower the flavor of the drink. Additionally, carbonic acid is easily formed and stable, making it a cost-effective and convenient choice for carbonating beverages.
