In which example is the final solution considered solid because of the solvent state?
Answer and explanation
Correct answer: Hydrogen in palladium
In hydrogen-in-palladium, hydrogen is the solute and palladium is the solid solvent or host metal. Because the continuous medium is solid, the overall solution is classified as a solid solution, specifically gas in solid. Salt, ethanol and oxygen in the other options are dissolved in liquid water, so those are liquid aqueous solutions.
