Chapter 7, Problem 4Q

Interpretation Introduction

Interpretation:

Weight of solute A that would be removed in four successive extractions with $25\text{ mL}$ portions of hexane should be calculated, and the amount of hexane required to remove $98.5\%$ of A in a single extraction should be determined.

Concept introduction:

The distribution coefficient is a parameter that indicates the extent of the solubility of two immiscible components in two different phases.One of the phases is aqueous, while the other is the organic phase.

Mathematically,

  $K_{\text{D}}=\frac{{\left[\text{solute}\right]}_{\text{org}}}{{\left[\text{solute}\right]}_{\text{aq}}}$
