Beer's Law states that A=ebc, where A is the absorbance, ε is the molar absorptivity of the solute, b is the path length, and c is the concentration. Identify the experimental evidence from the activity that you have for the dependence of absorbance on each variable

The evidence for the dependence of absorbance on the variable ε is:_________

a. increasing the cuvette width increases the absorbance.
b. changing the compound changes the absorbance behavior.
c. adding more water decreases the absorbance.

Answer:

b. changing the compound changes the absorbance behavior.

Step-by-step explanation:

  • Option a) would be akin to modifying the path length, b.
  • Option b) would involve using a different solute, as such, there would be another molar absortivity, ε.
  • Option c) would decrease the concentration (c) of the solute, which would explain why the absorbance would decrease as well.
