In which example do the solute and solvent have the same physical state?
Answer and explanation
Correct answer: Air
Air is a mixture of gases, mainly nitrogen with smaller amounts of other gases. The solute and solvent are therefore both gases, so it is a gas-in-gas solution. In soda water the solute is gas but the solvent is liquid; salt water is solid in liquid, and hydrogen in palladium is gas in solid.
