Which option has gaseous solute and solid solvent?
Answer and explanation
Correct answer: Hydrogen in palladium
Hydrogen is gaseous and palladium is a solid metal that can act as the solvent in this standard example. Hence hydrogen in palladium is a gas-in-solid solution. Camphor in nitrogen is solid-in-gas, air is gas-in-gas, and salt water is solid-in-liquid, so none of the distractors has the required pair of states.
