Chapter 13, Problem 13.25QAP
Interpretation Introduction
Interpretation:
As several absorbance values have been given under 440 nm, the most accurate way is to construct a graph between absorbance & the concentration of Cr2O72- solution. After using the value of slope & considering the chemical equation of Beer-Lambert law, absorptivity and the molar absorptivity of Cr2O72-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,
