In which pair are both solid solutions but the solute states are different?
Answer and explanation
Correct answer: Brass and hydrogen in palladium
The relevant principle is that the final solution can be solid even when the solute is not solid, because the solid solvent determines the overall state. Brass is a solid alloy containing solid metallic components. Hydrogen dissolved in solid palladium forms a solid solution, although hydrogen is a gas. Thus both examples are solid solutions, while their solute states are different. The remaining pairs are not both solid.
