Which pair can form a liquid in liquid solution?
Answer and explanation
Correct answer: Water and alcohol
Water and alcohol are both liquids and can mix uniformly, so one can act as the liquid solvent and the other as the liquid solute. Water and salt form a solid-in-liquid solution, while oxygen dissolved in water is gas in liquid. Copper and zinc are solid metals that can form a solid alloy. Therefore only water and alcohol fit liquid in liquid.
