Chapter 9, Problem 9D.3AST

Interpretation Introduction

Interpretation:

The concentration of ${\text{MnO}}_{\text{4}}{}^{\text{-}}$ has to be given.

Concept Introduction:

Beer’s lamberts law:

The Beer-Lambert law states that the quantity of light absorbed by a substance dissolved in a fully transmitting solvent is directly proportional to the concentration of the substance and the path length of the light through the solution.

  $\text{A=εLc}$

Where A is the absorbance of the solution,

$\text{ε}$ is the molar absorption coefficient.

L is the path length of the solution.

c is the concentration of the solution.
