Hydrogen dissolved in palladium is an example of which type of solution?
Answer and explanation
Correct answer: Gas in solid
Hydrogen is a gas, while palladium is a solid metal. When hydrogen is absorbed or dissolved in palladium, the gaseous solute is present in a solid solvent or solid medium. Therefore, it is classified as a gas-in-solid solution. The other choices reverse the states or introduce a liquid, so they do not fit this example.
