Which option correctly matches the state of a solution with its example?
Answer and explanation
Correct answer: Gaseous solution—air
Air is a homogeneous mixture of gases, so it is a gaseous solution and option A gives the correct match. Soda water and salt water have liquid water as their solvent, so they are liquid solutions. Brass is an alloy containing solid components and is therefore a solid solution. The remaining options mismatch the physical state of the example with the stated solution type.
