In which option is the type of solution not correct?
Answer and explanation
Correct answer: Glucose in water—solid in solid
A solution’s state description is written as solute state in solvent state. Air is gas in gas; hydrogen dissolved in solid palladium is gas in solid; and camphor dissolved in gaseous nitrogen is solid in gas. Glucose is a solid solute, but water is a liquid solvent, so glucose in water must be solid in liquid, not solid in solid. Therefore D is the incorrect classification.
