Linh is analyzing a solution in a crime lab. He needs to determine what liquid was used to dissolve the other substances. Which method would best complete the task?

Distillation heats the solution so the liquid with the lower boiling point vaporizes, then cools that vapor back into a liquid for collection. The collected liquid can be analyzed to determine what solvent dissolved the other substances. Evaporation would remove the liquid but would not collect it for testing, while filtration and decantation are not suited to separating dissolved substances from a solution.
