WebIn the cases with iron sand, Fig. 4 suggests that K from all three different potassium salts always managed to diffuse into the iron sand particles, independent of the initial oxidation states. Similar to ilmenite, molten phase with K and P enrichment from KH 2 PO 4 was formed between iron sand particles no matter what the initial oxidation ... Web3–, contains iron in the +3 oxidation state. A deep-blue (Prussian blue) precipitate results when either complex ion combines with iron in a different oxidation state from that present in the complex. The deep-blue color of the precipitate is due to the presence of iron in both oxidation states in the cyano complex. phosphotriesterase
