The undissociated form of a weak organic acid HA can be extracted...

The undissociated form of a weak organic acid HA can be extracted from the aqueous phase into an organic phase using a water-immiscible organic solvent according to the following scheme

Which of the following is/are correct for this extraction? I.

[\mathrm{HA}]_{\text {org }} /[\mathrm{HA}]_{\text {aq }}

depends on the pH of the aqueous phase II. HA can be efficiently extracted from basic aqueous solutions III.

[\mathrm{HA}]_{\text {org }} /[\mathrm{HA}]_{\text {aq }}

depends on the initial concentration of HA IV.

[\mathrm{HA}]_{\text {org }} /[\mathrm{HA}]_{\text {aq }}+ \left[\mathrm{A}^{-}\right]depends on the pH of the aqueous phase

Options

AII and IV
BIV only
CI only
DIII and IV

Correct answer

C. I only
