Soft drinks consist of which of the following gases?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Carbon dioxide.
- Soft drinks contain carbon dioxide.
- Carbon dioxide dissolves so well in water because it reacts and forms carbonic acid, which is the primary cause behind the 'fizz' of cold drinks.
- This process of adding carbon dioxide to beverages is called carbonation.
Other Options:
Sulfur dioxide (SO2) is a colorless, toxic gas with a pungent odor, often described as smelling like burnt matches.
Carbon monoxide (CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air.
