Which example has a gaseous solute and a solid solvent?
Answer and explanation
Correct answer: Hydrogen in palladium
Hydrogen is a gas and palladium is a solid metal. When hydrogen is absorbed into palladium, hydrogen serves as the gaseous solute and palladium serves as the solid solvent, giving a gas-in-solid solution. Salt and sugar in water are solid-in-liquid examples, while ethanol in water is liquid-in-liquid. Therefore, option A is the only suitable example.
