Which option has a gaseous solute but the solution is not gaseous?
Answer and explanation
Correct answer: Carbon dioxide in water
The governing concept is that the physical state of a solution is generally identified by its solvent, while the solute may have a different state. In option A, carbon dioxide is a gaseous solute and water is a liquid solvent, so the result is a gas-in-liquid, liquid solution. In B, C, and D, the solvents are gases, so those mixtures are gaseous solutions.
