Given that the formation of a complex ion gives rise to the peak near 450 nm in the absorbance spectrum, why should the solution prepared by combining 5 mL 0.00200 M KSCN in 0.50 M HNO3(ml) with 5 mL of 0.00200 M Fe(NO3)3 in 0.50 M HNO3(ml) give a higher absorbance than the other combinations of volumes studied?
