SSC Selection Post - Matriculation Level - 04 Aug 2022 - Shift 1 • General Awareness • Q35

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.

Nitrogen gas (N2) is a colorless, odorless, and tasteless gas that constitutes about 78% of the Earth's atmosphere.
