Homework Answers
Which solvent will be above which one will be below in a separatory funnel in a liquid / liquid extraction depends all on the density of these solvents , more denser will be below and less denser will be up.
In chloroform with water , chloroform is more denser than water so chloroform will be below and water will be above in a separatory funnel in a liquid / liquid extraction.
In case of hexane with water, water is more denser than hexane so water will be below and hexane will be above in a separatory funnel in a liquid / liquid extraction .

Laboratory Date Name TA Experiment 2- Post- lab Questions I. Chloroform and cyclohexane are organic liquids that are insoluble in water (see Table 2.2), and this causes two distinct liquid phases, an organic phase and a water phase, to form when these organic liquids are mixed with water. However, in a chloroform/water mixture, the water phase is on the top and the organic chloroform phase is on the top, whereas in a cyclohexane/water mixture, the water phase is on the...

You have a separatory funnel that contains a solution of 4-methyl benzoic acid and ethoxybenzene in methylene chloride. By adding KOH (aq) into this solution for extraction, what compound(s) would be expected to form in the aqueous layer? Write the equation. Compound X has a hexane/water distribution coefficient of 2.0. (a) Does compound X have a higher or lower solubility in hexane comparing to water? (b) How much of a 3.0 g sample of compound X dissolved in 100 ml...

a) After the reaction is completed, the reaction mixture is
transfered to a separatory funnel. The layers are separated and the
organic layer is washed with each of the following: an equal amount
of saturand NaCl, satured NaHCO3, deionized H2O, and again with
saturated NaCl. This is an example of a "basic" work-up. Illustrate
what is being neutralized in this work up using a balanced
equation. (2 Marks)
