Chapter 18, Problem 18.11P

Interpretation Introduction

Interpretation:

Value of absorbance at indicated transmittance values has to be calculated.

Concept Introduction:

Expression to compute absorbance as per Beer’s law is as follows:

  $A=\epsilon \cdot b\cdot c$

Expression to compute transmittance from absorbance is as follows:

  $A=-\log T$

Here,

$\epsilon$ denotes molar absorptivity of species capable top absorb.

$b$ denotes path length in centimeters.

$c$ denotes concentration of species capable top absorb

$A$ denotes absorbance.

$T$ denotes transmittance.
