Question

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

Answer 1

Density of hexane is 0.659g/mL

Density of water is 1g/mL

Density of chloroform is 1.4g/mL

So in first experiment water will form lower layer as it has greater density

In second experiment chloroform will form lower layer due to greater density.
