Which statement gives the most correct chemical understanding of air?

Answer and explanation

Correct answer: Air is a homogeneous solution of gases

Air contains nitrogen, oxygen, argon, carbon dioxide, water vapour, and other gases in variable proportions. When these gases are uniformly mixed, air behaves as a homogeneous gaseous mixture, commonly described at this level as a gas-in-gas solution. It is neither a pure substance nor only oxygen.
