For this type of quantitative analysis, you need to be as exact as … WebColorimetric determination of Fe(III) by the thiocyanate method. Trivalent iron ions form red complex with SCN-ions at acidic pH solution. The maximum of absorption of this complex is situated at wavelength max =480 nm. In excess of thiocyanate, mainly 5:1 complex is formed, which has also the strongest red color.
