ANALYSIS OF IRON COORDINATION COMPOUND A redox titration with potassium permanganate solution will be utilized to determine both the iron and oxalate ion content of the K3[Fe(C2O4)3] 3H2O compound and will therefore provide both a verification of the composition of the compound and as assessment of its purity.

What colour light does ferrioxalate absorb?

The ferrioxalate complex absorbs light at the blue end of the visible light spectrum resulting in an internal electron transfer reaction in which Fe3+ is reduced to Fe2+. Potassium hexacyanidoferrate(III), K3[Fe(CN)6], then reacts with the Fe2+ ions to produce a component with a deep blue colour called Prussian blue.

What wavelength absorbs ferrioxalate?

Nicodem and Aquilera [6] found that the quantum yield of the ferrioxalate actinometer is temperature independent over the range 5–80 ◦C. from its spectral absorption maximum at 352 nm. The advantage of this actinometer is that it can be used in room light, since it is not sensitive to UV light of > 320 nm.
