Which pair can form a solid in liquid solution?
Answer and explanation
Correct answer: Sugar and water
Sugar is a solid and water is a liquid. When sugar dissolves in water, it forms a homogeneous solid-in-liquid solution. Oxygen in water is a gas-in-liquid example, water and alcohol are both liquids, and nitrogen with oxygen is a gas-gas mixture. Thus the states of the two substances identify sugar and water as the only correct pair.
