b. Beer's Law
Introduction This on-line learning module introduces students to Beer’s law with particular attention to the relationships between absorbance, transmittance, and power, and to the fundamental, instrumental, and chemical limitations inherent in the […]
Students will learn to:
Describe the relationship between absorbance and transmittance.
Develop a proportional relationship between absorbance and concentration.
Account for the role of sample pathlength in absorbance measurements.
Determine the molar absorptivity of a compound based on its absorbance behavior according to Beer’s Law.
Construct a spectrum from absorbance measurements at various concentrations.
Students explore Beer’s law and calculations that arise from applying Beer’s law.
