Chapter 14, Problem 14.21QAP

Interpretation Introduction

Interpretation:

The formation constant for the process ${\text{Cu}}^{2+}{\text{ + 2 A}}^{2-}\rightleftharpoons {\text{ CuA}}_2^{2-}$ under given conditions should be calculated.

Concept introduction:

The Beer-Lambert Law is:

$A=\epsilon lc$

A − absorbance

$\epsilon$ - molar absorptivity

l − length of the solution light passes through (cm)

c − concentration of solution (mol/L)

Formation constant is the equilibrium constant for the formation of complex in a solution. This is also known as stability constant.
