In which pair are both liquid solutions but the solute states are different?
Answer and explanation
Correct answer: Salt in water and oxygen in water
The governing idea is that a solution is classified by its overall state, usually the state of its solvent, while the solute may have a different state. In salt water, salt is a solid solute and water is liquid; in oxygenated water, oxygen is a gaseous solute and water is liquid. Thus both are liquid solutions, but the solute states differ. The other pairs do not meet both conditions.
