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

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. hope it helps

Answer 2

For layer formation in a solution that has water in it the density of whatever is mixed in water is most important considering which the cases of formation of layers happens.

In the given question there are two cases of mixing of liquid with water

1) In this case hexene is mixed with water. Hence it would form the upper layer as vaccine is a liquid that is non polar in nature and has a density that is lower than water hence would float over Water.

2) In this case chloroform is mixed with water and this element being heavier in density than that of water would move downward and water shall form the upper layer .
