In which example is the solute gas and solvent solid while the solution is considered homogeneous?
Answer and explanation
Correct answer: Hydrogen in palladium
Hydrogen is a gas that can dissolve within the solid structure of palladium, the solid solvent. When the hydrogen is uniformly distributed, the material is treated as a homogeneous gas-in-solid solution. Camphor in nitrogen is solid-in-gas, soda water is gas-in-liquid, and salt water is solid-in-liquid.
