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 CrO 42- 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 = c l ε

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 CrO42- 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=clε
