Chapter 23, Problem 23.9P

Interpretation Introduction

Interpretation:

The fraction of solute remaining in the aqueous phase has to be calculated.

Concept introduction:

Fraction of solute:

Fraction remaining in one phase after $\text{n}$ extractions is given by

$\begin{array}{l}{\text{q}}^{\text{n}}\text{=}\left(\frac{{\text{V}}_{\text{1}}}{{\text{V}}_{\text{1}}\text{+}{\text{KV}}_{\text{2}}}\right)\\ \text{where,}\\ {\text{q}}^{\text{n}}\text{-}\text{fraction}\text{remaining}\text{after}n\text{extractions}\\ {\text{V}}_{\text{1}}\text{-}\text{volume}\text{of}\text{phase}\text{1}\\ {\text{V}}_{\text{2}}\text{-}\text{volume}\text{of}\text{phase}\text{2}\\ \text{K}\text{-}\text{partition}\text{coefficient}\text{.}\end{array}$
