In which example is water not the solvent?
Answer and explanation
Correct answer: Air
In sugar water, salt water, and glucose solution, water is the substance that dissolves the other component, so it acts as the solvent. Air is a mixture of gases, chiefly nitrogen, oxygen, and other gases; water is not its solvent. Therefore, air is the only suitable choice. The question asks where water is not the solvent, not whether water vapour may be present in air.
