In which example do components of the same state combine to form a solution?
Answer and explanation
Correct answer: Water and ethanol
Water and ethanol are both liquids at room temperature and can mix uniformly, producing a liquid-in-liquid solution. In oxygen in water, the components are gas and liquid; in salt in water they are solid and liquid; and in hydrogen in palladium they are gas and solid. Therefore only water and ethanol have components initially in the same physical state.
