Which option has a gaseous solvent and a gaseous solute?
Answer and explanation
Correct answer: Oxygen in nitrogen
The relevant principle is classification by the physical states of the solute and solvent. In option A, oxygen is the gas solute and nitrogen is the gas solvent, so the mixture is a gas-in-gas solution. Option B is gas in liquid, option C is gas in solid because palladium is solid, and option D is solid in liquid because glucose is solid and water is liquid.
