What is the main difference between ethanol in water and oxygen in water?
Answer and explanation
Correct answer: In the first, the solute is liquid; in the second, the solute is gas
Ethanol is a liquid, so in ethanol-in-water it is the liquid solute; water remains the liquid solvent. Oxygen is a gas, so in oxygen-in-water it is the gaseous solute, while water is again the liquid solvent. Thus the solvents have the same state, but the solutes have different states. The other statements incorrectly describe the components.
