A student has performed an experiment in the laboratory. He mixed water with hexane and found two layers separated. A second time he mixed chloroform with water and he again found two layers in the test tube. Explain which will be an upper layer and which one will be a lower layer in both the experiments.

Solution

Since hexane is non polar in nature and have lower density than water it will be upper layer.
In second case chloroform will be in the lower layer because it is more dense than water.
