Why was creating a Beer's Law plot necessary? Choose the best answer. Group of answer choices in order to determine the amount o
f Fe2+ in the saturated iron (II) oxalate solution in order to monitor the degree of saturation over time in the iron (II) oxalate solution in order to determine how well Fe2+ complexes with phenanthroline in order to monitor the kinetics of the reaction between Fe2+ and oxalate
Once the absorbance vs. concentration is plotted, the equation for the slope of the line and the average absorbance can be used to calculate the amount of iron (II) in a solution.
