(a) Interpretation: The direction of the reaction C(s) + H 2 O(g) ⇌ CO(g) + H 2 (g) when the volume is increased should be predicted. Concept introduction: Le Chatelier’s principle states that if a change in pressure, temperature or concentration of reactant or product is applied to a system in equilibrium, the equilibrium shifts in such a way to counteract that change. Boyle’s law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at constant temperature.

You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you
manipulated and exploited the acid-base chemistry of one or more of the compounds in your
mixture to facilitate their separation into different phases. The key to understanding how liquid-
liquid extractions work is by knowing which layer a compound is in, and in what protonation state.
The following liquid-liquid extraction is different from the one you performed in Experiment
4, but it uses the same type of logic. Your task is to show how to separate apart Compound
A and Compound B.
. Complete the following flowchart of a liquid-liquid extraction. Handwritten work is
encouraged.

Draw by hand (neatly) only the appropriate organic compound(s) in the boxes.
.
Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4
and 5.
•
Box 7a requires the solvent (name is fine).
•
Box 7b requires one inorganic compound.
