Which option gives a correct example and reason for a gas in gas solution?
Answer and explanation
Correct answer: Air, because gases are uniformly mixed.
Air is a homogeneous gas-in-gas solution or gaseous mixture. In the usual school-level description, nitrogen is the major gaseous component and acts as the solvent, while oxygen, carbon dioxide, and noble gases are solutes. Brass is a solid-in-solid alloy, salt water is solid in liquid, and an amalgam contains metals rather than gases. Hence A alone gives the correct example and reason.
