Chapter 11, Problem 11A.2AE

Interpretation Introduction

Interpretation:

The percentage reduction in intensity of ultraviolet radiation has to be calculated when it passes through a solution of $4.25{\text{ mmol dm}}^{-3}$ concentration and $2.50\text{mm}$ length.

Concept introduction:

The Beer-Lambert law states that the intensity of light absorbed by a solution is directly proportional to the concentration of the solution and the path length of that the light has to travel in the solution.  The mathematical expression for Beer-Lambert law is given below.

    $A=\epsilon cL$
