In which option do all examples have a liquid solvent?
Answer and explanation
Correct answer: Salt in water, ethanol in water, carbon dioxide in water
The key rule is to identify the solvent in every example, not simply the solute. In option A, water is the solvent in all three cases—salt in water, ethanol in water, and carbon dioxide in water—and water is liquid. Option B and much of D involve solid metallic solvents, while C contains gaseous solvents such as air and nitrogen. Hence A is the only complete group.
