Which option includes both solid in solid and gas in solid types?
Answer and explanation
Correct answer: Brass and hydrogen in palladium
Brass is a solid-in-solid solution because its metallic components are solids. Hydrogen in palladium is gas-in-solid because hydrogen is gaseous and palladium is the solid solvent. Both therefore have solid solvents, while the other options contain gaseous or liquid solvents and cannot provide both requested types.
