The Partition Coefficient Is Modified When the PH of the Aqueous

Multiple Choice

The partition coefficient is modified when the pH of the aqueous phase is adjusted or when a chelating agent is added.The partition coefficient is renamed the distribution coefficient.What is the impact on the extraction of a weak acid into an organic solvent as the pH of the aqueous phase increases?

A) As the pH increases the value of D decreases and the percentage weak acid left in the aqueous phase decreases.
B) As the pH increases the value of D increases and the percentage weak acid left in the aqueous phase increases.
C) As the pH increases,the value of D decreases and the percentage weak acid left in the aqueous phase decreases.
D) As the pH increases the value of D increases and the percentage weak acid left in the aqueous phase decreases.
E) As the pH increases the value of D decreases and the percentage weak acid left in the aqueous phase increases.
