If a solution has a solid solvent and a liquid solute, which can be a correct example?
Answer and explanation
Correct answer: Mercury in sodium
A solid-in-liquid arrangement does not fit the condition, so the example must contain a solid solvent and a liquid solute. Mercury is liquid, whereas sodium is a solid metal; a mercury–sodium amalgam can represent a liquid solute in a solid metallic solvent. Salt in water is solid in liquid, oxygen in water is gas in liquid, and air is gas in gas.
