Title: Trying to Find Molar Attenuation Coefficient of FeSCN2+
Post by: erik1234 on December 26, 2020, 04:26:01 PM

For my IB Chemistry IA, I am trying to find the molar attenuation coefficient of FeSCN2+, and the values I currently have are the concentrations of the reactants, which were KSCN and Fe3+ and the absorbance of FeSCN2+. I was struggling to find a way to calculate the molar attenuation coefficient using the data I have, and after conducting some research I'm not sure if it is possible to do given my current data set. I have tried graphing the change in abosrbance against the change in concentration of KSCN, but that has not lead me to find any way to calculate the molar attenuation coefficient.
Is there a way to graphically deteremine the molar attenuation coefficient of FeSCN2+, or is it impossible given the current data set?
