Chapter 23: Q4P (page 629)

(a) Why is it difficult to extract the complex of aluminum into an organic solvent but easy to extract the complex?
(b) If you need to bring the $EDTA$ complex into the organic solvent, should you add a phase transfer agent with a hydrophobic cation or a hydrophobic anion?

Short Answer

Expert verified

A hydrophobic cation is needed to bring the hydrophobic complex to the organic solvent.

Step by step solution

of 2

(a)

Here, it is to be noted that that $EDTA$ complex with aluminium is in the anionic form $AI {[EDTA]}^{-}$
Here, $8 - hydroxyquinoline$ complex with aluminium is neutral $AI {[8 - hydroxyquinoline]}_{3}$ .

neutral species are more soluble in an organic solvent, and the charged species are more soluble in aqueous

of 2

(b)

As, $EDTA$ complex is in anionic form, we would need a hydrophobic cation to bring the hydrophobic complex to the organic solvent.

Result:

A hydrophobic cation is needed to bring the hydrophobic complex to the organic solvent as $EDTA$ complex is in anionic form.
