Chapter 8, Problem 8.42AP

Interpretation Introduction

Interpretation:

An explanation corresponding to the fact that the complex of the crown ether $\left[18\right]\text{-crown-6}$ with potassium ion shows larger dissociation constant in water than in ether is to be stated.

Concept introduction:

The crown ether $\left[18\right]\text{-crown-6}$ consists of a cyclic ring of eighteen membered with six ester linkage.

Dissociation constant is defined as the quantity that shows the extent of dissociation of a specific substance into ions in solution. It is expressed as the product of the concentrations of the respective ions that is divided by the concentration of the molecule which remain undissociated.
