When two immiscible liquids are mixed together, the less dense layers is a top layer and the more dense layer forms the bottom layer.
The densities of the solvents are given below:
Water – 1000 kg/m3;
Hexane – 655 kg/m3;
Chloroform – 1490 kg/m3.
Therefore, when hexane and water are mixed, the upper layer is hexane, because hexane is less dense. When chloroform and water are mixed, the upper layer is water, because water is less dense.
