Which option correctly writes the type of solution according to the states of solute and solvent?
Answer and explanation
Correct answer: Gaseous solute and solid solvent: gas in solid solution
The naming rule lists the solute state first and the solvent state second. Therefore, a gaseous solute dissolved in a solid solvent is a gas-in-solid solution, exactly as stated in option A. In B, C, and D, the named type reverses or changes at least one given state: solid-liquid becomes liquid-solid, liquid-gas becomes gas-liquid, and gas-liquid becomes liquid-gas.
