Which option correctly matches a gaseous solute with a liquid solvent?
Answer and explanation
Correct answer: Oxygen in water
Oxygen is a gas and water is a liquid. When oxygen dissolves in water, it forms a gas-in-liquid solution, so option A has exactly the required combination. Sugar in water is solid in liquid, zinc in copper is solid in solid, and water vapour in air is gas in gas because air is gaseous. Therefore only option A correctly matches a gaseous solute with a liquid solvent.
