If a solution has a gaseous solvent and a liquid solute, which example is most suitable?
Answer and explanation
Correct answer: Chloroform in nitrogen
To solve this, identify the state of the dissolved substance first and the medium second. Chloroform is a liquid solute, while nitrogen is a gaseous solvent; therefore chloroform in nitrogen is liquid in gas and matches both conditions. Ethanol in water is liquid in liquid, oxygen in water is gas in liquid, and hydrogen in palladium is gas in solid. Hence B is the only suitable example.
