In which example is the solute a gas but the final solution a solid?
Answer and explanation
Correct answer: Hydrogen in palladium
Hydrogen is a gas and is taken as the solute in this example. Palladium is a solid metal that serves as the solvent or host. Since the solvent is solid, the resulting homogeneous mixture is classified as a solid solution, often described as gas-in-solid. Soda water and oxygen in water have liquid solvents, while air is gas in gas.
