Which example has a gaseous solvent and belongs to the homogeneous gaseous category?
Answer and explanation
Correct answer: Air
Air is a uniform mixture of gases such as nitrogen, oxygen, and smaller amounts of other gases. The major component, usually nitrogen in ordinary dry air, acts as the solvent, while the other gases act as solutes. Since the solvent is gaseous and the mixture is homogeneous, air is a gaseous solution. Salt water and glucose water are liquid solutions, while brass is solid.
