Question

Suppose that you are given two unlabeled beakers. One beaker contains water, and the other beaker contains a solution of ethanol and water. How could you safely determine which beaker contains just water?

Answer 1

You could smell each beaker since water does not have a specific scent while ethanol does

Answer 2

Simple distillation

Step-by-step explanation:

If the contents of the two beakers are distilled, water boils at 100oc and pure water is collected. The other solution will not boil at 100oc, it will boil at a lower temperature and two fractions will be collected after simple distillation.
