In which example is the final solution solid but the solute is gaseous?
Answer and explanation
Correct answer: Hydrogen in palladium
The governing principle is that the solvent usually determines the final physical state of a solution. In hydrogen dissolved in palladium, hydrogen is the gaseous solute and palladium is the solid solvent, so the final solution is solid. Oxygen in water and glucose in water are liquid solutions, while chloroform in nitrogen is gaseous. Therefore option B is correct.
