eli5: Why is co2 the gas used to pressurize drinks. Why can’t something like nitrogen or atmosphere air be used.

Carbonated water creates carbonic acid which gives a little sting and sourness to your drink and tickles your nose when the bubbles burst at the top.

Nitrogen infusion gives a creamy texture and it's used in beer and coffee.

Oxygenated water is advertised as having health benefits, but at high amounts of infusion you start getting hydrogen peroxide, with is not good to drink.

Just using regular air is basically nitrogen and oxygen.
