Chapter 5.3, Problem 5E

(a)

Interpretation Introduction

Interpretation: Thegrams of compound A that could be removed from 400 mL of an aqueous solution by single extraction that contains 12 g of compound A needs to be determined.

Concept Introduction:A solution is a mixture of solute and solvent. To separate the solute from the solution, different separation methods can be used. Separatory funnel is one of the most common method in which a separatory funnel is taken in which the solution is and shaken with an immiscible solvent. Solute distributes between both solvents to form two layers. At equilibrium the ratio of concentration of solute is constant in each layer that can be represented by partition coefficientordistribution coefficient. It is the ratio of the concentration of a substance in one medium (C₁) to the concentration in a second medium (C₂) at equilibrium.
