In which example is the final solution gaseous while the solute is solid?
Answer and explanation
Correct answer: Camphor in nitrogen
A solution is classified largely by the state of its solvent, which forms the continuous medium. In camphor in nitrogen, camphor is the solid solute and nitrogen is the gaseous solvent, so the final solution is gaseous. Hydrogen in palladium and copper in gold are solid solutions because their solvents are solids, whereas glucose in water is a liquid solution. Hence A is correct.
