In which example are the physical states of solute and solvent different?
Answer and explanation
Correct answer: Salt in water
The governing idea is to compare the physical states of the solute and solvent. In salt water, salt is a solid solute and water is a liquid solvent, so their states are different and the mixture is a solid-in-liquid solution. Air contains gaseous components, brass contains solid components, and water-alcohol is liquid-in-liquid. Hence option A is correct.
