Sodium ferrocyanide is the sodium salt of the coordination compound of formula [Fe(CN) 6] 4−. In its hydrous form, Na 4 Fe(CN) 6 · H 2 O (sodium ferrocyanide decahydrate), it is sometimes known as yellow prussiate of soda. It is a yellow crystalline solid that is soluble in water and insoluble in alcohol. The yellow color is the color of ...
Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment.

For example, Cu compounds with Cu oxidation state +2 are called cupric and those with state +1 are cuprous. [4]: 172 The oxidation numbers of elements allow predictions of chemical formula and reactions, especially oxidation-reduction reactions. The oxidation numbers of the most stable chemical compounds follow trends in the periodic table.
For example, consider the overall reaction for aerobic cellular respiration: C 6 H 12 O 6 (s) + 6O 2 (g) → 6CO 2 (g) + 6H 2 O(l) The oxygen (O 2) is being reduced, so it is the oxidizing agent. The glucose (C 6 H 12 O 6) is being oxidized, so it is the reducing agent.
2 H 2 O ⇌ O 2 + 4 H + + 4 e − (anode: oxidation) When solving the Nernst equation for each corresponding reduction reaction (need to revert the water oxidation reaction producing oxygen), both equations have a similar form because the number of protons and the number of electrons involved within a reaction are the same and their ratio is ...
A representative example is the reaction of hydrogen with Vaska's complex, trans-IrCl(CO)[P(C 6 H 5) 3] 2. In this transformation, iridium changes its formal oxidation state from +1 to +3. The product is formally bound to three anions: one chloride and two hydride ligands. As shown below, the initial metal complex has 16 valence electrons and a ...
One example is the zero-valent [Fe(CO) 4 (CN)] −. Heteroleptic cyanometallates are of interest outside of the research laboratory, with one example being the drug sodium nitroprusside (Na 2 FeNO(CN) 5 ).
