In which example will the state of the solution differ from the solute but match the solvent?
Answer and explanation
Correct answer: Carbon dioxide in water
In an ordinary solution, the solvent usually determines the physical-state description of the final solution. Carbon dioxide is a gas, whereas water is a liquid, so carbon dioxide dissolved in water is treated as a liquid solution; its state differs from the gaseous solute and matches the liquid solvent. In B both are gases, in C both are solids, and in D both are liquids.
