Why is it generally preferable to use absorbance as a measure of absorption rather than %T?
Understand the Problem
The question is asking for the reasons why absorbance is typically favored over percent transmittance (%T) as a measurement for absorption in scientific contexts, particularly in spectrophotometry. This involves understanding the advantages of using absorbance, including its linear relationship with concentration and the inherent logarithmic nature of light absorption.
Answer
Absorbance has a straightforward linear relationship with concentration.
Using absorbance is preferred over % transmittance because absorbance has a straightforward linear relationship with concentration, making it easier to interpret and apply the Beer-Lambert law.
Answer for screen readers
Using absorbance is preferred over % transmittance because absorbance has a straightforward linear relationship with concentration, making it easier to interpret and apply the Beer-Lambert law.
More Information
Absorbance is logarithmically related to % transmittance, making calculations and interpretations more intuitive and less error-prone.
Tips
Avoid assuming that % transmittance and absorbance can be used interchangeably; the linearity of absorbance with concentration is key for accurate quantitative analysis.
