Solution Summary

This solution discusses the upper and lower phases of solvents when mixed with water.

Solution Preview

When 2 immiscible liquids separate into phases, where the organic layer ends up is determined by the relative densities of the liquids. Pure water has a density of 1g/cm3 (mL).

If the density of the organic phase is less than 1 ...
