In which option does the solute state change while the solvent remains liquid?
Answer and explanation
Correct answer: Salt in water and oxygen in water
In salt water, salt is a solid solute and water is the liquid solvent. In oxygenated water, oxygen is a gaseous solute and water remains the liquid solvent. Thus the solute state changes from solid to gas while the solvent state stays liquid in both examples. The other pairs change the solvent state or do not provide two liquid-solvent examples.
