Question

8. Why is it typically advisable (especially when using Beer's law) to make absorbance measurements at a wavelength that produces a maximum and not some other (random or otherwise different) wavelength? [1pt] 9. What difference(s) would you see in the standard curve (the graph sketched below Table 1) if a wavelength of 500nm was used for obtaining absorbance data (think about slope, y-intercept, scale, etc.)? Explain. [2pt]

Step 1

Beer's Law states that the absorbance (A) of a solution is directly proportional to its concentration (c) and the path length (l) through which the light passes. Mathematically, this is represented as: A = εcl where ε is the molar absorptivity, which is a Show more…
