Which option has solute and solvent in the same physical state?
Answer and explanation
Correct answer: Ethanol in water
Ethanol is liquid and water is also liquid, so the two components have the same physical state. Ethanol acts as the solute and water as the solvent, making a liquid-in-liquid solution. Salt is solid, oxygen is gas, and hydrogen is gas while palladium is solid, so the other pairs contain unlike states.
