Problem 7P
When water is shaken with hexane, the two liquids separate into two phases. Which compoundis present in the top phase, and which is present in the bottom phase? When water is shakenwith chloroform, a similar two-phase system results. Again, which compound is present ineach phase? Explain the difference in the two experiments. What do you expect to happenwhen water is shaken with ethanol (CH3CH2OH)?

Step 1:
This question can be answered using the concept of density of liquids.
Density is nothing but mass per unit volume. Simply put, it is the measurement of how tightly a substance is composed of. The unit of density is g/cm3.
All liquids have unique density. The density of liquids is the property of a liquid that determines which liquid floats and which liquid sinks when two liquids are mixed together. The liquid with higher density sinks and the liquid with lesser density floats.
