A client wants to determine the concentration of his sample, FESCN²* solution. To be able to do this, the new analyst in your company prepared different concentrations of ferric chloride reacted with potassium thiocyanate solution forming solutions of varying hues of red-orange depending on the concentration of the bloody-red complex, FESCN²*.Since the analyst is new to the company, he does not know at wavelength he should be working on.

Experiment 10 Spectrophotometry
A client wants to determine the concentration of his sample, FESCN2* solution. To be able to do this, the new analyst in your
company prepared different concentrations of ferric chloride reacted with potassium thiocyanate solution forming solutions of
varying hues of red-orange depending on the concentration of the bloody-red complex, FeSCN2*.Since the analyst is new to the
company, he does not know at wavelength he should be working on. Should he work at 447 nm or at 680 nm?
a. Please help your analyst by stating the correct wavelength and the reason why he should be working on that wavelength.
