Chapter 13, Problem 13.24QAP

Interpretation Introduction

Interpretation:

As several absorbance values have been given under 375 nm, the most accurate way is to construct a graph between absorbance & the concentration of CrO_{42- solution. After using the value of slope & considering the chemical equation of Beer-Lambert law, absorptivity and the molar absorptivity of CrO42- should be calculated.}

Concept introduction:

The absorbance of light can be determined by the Beer-Lambert law. The chemical equation relevant to the law is,

$A=cl\epsilon$
