Why is air considered a solution rather than a pure substance?
Answer and explanation
Correct answer: Several gases are uniformly mixed in it
A pure substance contains one chemical component with a fixed composition, whereas air contains several gases such as nitrogen, oxygen, and smaller amounts of other gases. These components are mixed on a molecular scale, so air is treated as a homogeneous gas-in-gas solution. It is not pure merely because it appears uniform.
