In which pair are both gaseous solutions but the solute states are different?
Answer and explanation
Correct answer: Air and chloroform in nitrogen
A solution’s overall state is determined mainly by its solvent. Air is a gas-in-gas solution, so its solute components are gases. In chloroform dissolved in nitrogen, chloroform is a liquid solute and nitrogen is a gaseous solvent; the resulting solution is gaseous. Therefore both solutions are gaseous, but their solute states differ. The other pairs are liquid or solid solutions.
