If a homogeneous mixture has a solid solvent and a gaseous solute, which example is correct?
Answer and explanation
Correct answer: Hydrogen in palladium
The governing rule is that the solvent is the medium in which the solute dissolves, while the solution is named by the states of both components. Palladium is a solid metal that can absorb hydrogen; therefore hydrogen is the gaseous solute and palladium is the solid solvent. This makes A a gas-in-solid solution. B is gas in liquid, C is gas in gas, and D is solid in liquid.
