Most halogenated solvents are denser than water, most non-halogenated solvents are less dense than water. Two phases should be observed. It employs a set of techniques based on the principle of selective retention to separate the components of a mixture in a high state of purity, or to identify them in a mixture and determine their exact proportion . Separatory funnels work on the principle that immiscible liquids will separate from each other naturally along with their solutes, creating different layers of solution-solute. Let it stand undisturbed for sometime so that separate layers of oil and water are formed. What likely happened is that the wrong layer was added to the separatory funnel - for example the organic layer was unknowingly added instead of the aqueous layer.
