How would you go about separating a mixture of 1-chloro-4-methylbenze and salicylic acid using extraction? Describe the procedure in detail and identify whether each component of the mixture is acidic, basic, or neutral.

Carboxylic acids are acidic enough to dissolve in both 10% NaOH and NaHCO3. Phenols, ArOH, are weak acids and most phenols will not dissolve in 10% NaHCO3. How would you separate a mixture of a carboxylic acid (RCOOH), an amine (RNH2), a phenol (ArOH) and a hydrocarbon (RH) using chemically active extraction? Draw a flow chart to illustrate your separation. Show each species in the aqueous and organic layers.

Write an equation for the reaction of chloroacetic acid (Ka=1.5103) with trimethylamine (Kb=5.9105) . Calculate the equilibrium constant for the reaction. If 0.10 M solutions of these two species are mixed, what will be their concentrations at equilibrium?

You have a mixture of an aryl halide and a carboxylic acid that you wish to separate (both are solids). Both are soluble in diethyl ether. Explain ALL the steps you would take to obtain the two compounds in pure form from your sample.
