What is the best reason for considering air a homogeneous solution?
Answer and explanation
Correct answer: Its gases are uniformly mixed
Air contains a mixture of gases, mainly nitrogen and oxygen along with smaller amounts of other gases. In ordinary clean air, these gases are distributed uniformly, so a sample has essentially the same composition throughout and is treated as a homogeneous gaseous solution. Air is not pure oxygen, a liquid, or a mixture made only of solids. Therefore, option A is correct.
