Why is a mixture of chloroform in nitrogen considered a gaseous solution?
Answer and explanation
Correct answer: Because the solvent is gas
The governing concept is that the physical state of a solution is generally identified by the solvent, which forms the continuous medium. In this mixture, chloroform is the liquid solute but nitrogen is the gaseous solvent. Therefore the resulting solution is classified as gaseous. The solute need not be a gas, and neither solids nor water are involved, so B is correct.
