Glyoxyhc acid gives a yellow 1:l complex, [Fe-CHOC00]2+ with iron(II1). The dissociation constant, measured by two spectrophotometric methods, is K = 9.7 + 1 mol 1-l. Oxalic acid gives two complexes with iron(II1) which absorb in the same range around 400 nm. With appropriate precautions and correct
