(a) Interpretation: The concentrations of A and B in solution should be determined that yielded absorbance 0.439 at 475 nm and 1.025 at 700 nm. Concept introduction: The Beer-Lambert Law is: A = ε l c A − absorbance ε - molar absorptivity l − length of the solution light passes through (cm) c − concentration of solution (mol/L)

Solutions

Chapter 14, Problem 14.9QAP
Interpretation Introduction

(a)

Interpretation:

The concentrations of A and B in solution should be determined that yielded absorbance 0.439 at 475 nm and 1.025 at 700 nm.

Concept introduction:

The Beer-Lambert Law is:

A=εlc

A − absorbance

ε - molar absorptivity

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

c − concentration of solution (mol/L)

Interpretation Introduction

(b)

Interpretation:

The concentrations of A and B in solution should be determined that yielded absorbance 0.662 at 475 nm and 0.815 at 700 nm.

Concept introduction:

The Beer-Lambert Law is:

A=εlc

A − absorbance

ε - molar absorptivity

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

c − concentration of solution (mol/L)
