Which option is not a solid solution?
Answer and explanation
Correct answer: Sugar water
Brass and bronze are solid alloys, and copper mixed uniformly into gold is also a solid-in-solid mixture. In each case, the solvent is a solid metal and the resulting solution remains solid. Sugar water is different: sugar is the solid solute, but water is a liquid solvent, so the result is a liquid solution. Therefore sugar water is not a solid solution, making option D correct.
