(III) Hg in Na |
(A) Solid in solid → (II) Cu in Au (Copper dissolved in gold forms a solid alloy, a classic example of a solid-in-solid solution.)
(B) Solid in gas → (I) Camphor in N₂ (Camphor sublimes and mixes with nitrogen gas, forming a solid-in-gas solution; nitrogen is specified to avoid oxidation in air.)
(C) Gas in solid → (IV) H₂ in Pd (Hydrogen gas absorbed into palladium metal, a well-known gas-in-solid solution.)
(D) Liquid in solid → (III) Hg in Na (Mercury (liquid) dissolved in sodium (solid) forms a sodium amalgam, an example of a liquid-in-solid solution.)
