    For example, it will react with diluted sulfuric acid under heating forming potassium sulfate, ferric sulfate and hydrogen cyanide. 2 K 3 [Fe(CN) 6] + 6 H 2 SO 4 → 3 K 2 SO 4 + Fe 2 (SO 4) 3 + 12 HCN. This won't occour with concentrated sulfuric acid as hydrolysis to formic acid and dehydration to carbon monoxide will take place instead. [17]

    For example, the complex [Ni(dien) 2)] 2+ is more stable than the complex [Ni(en) 3)] 2+; both complexes are octahedral with six nitrogen atoms around the nickel ion, but dien (diethylenetriamine, 1,4,7-triazaheptane) is a tridentate ligand and en is bidentate. The number of chelate rings is one less than the number of donor atoms in the ligand.

    en.wikipedia.org/wiki/Job_plot

    An observable that is proportional to complex formation (such as absorption signal or enzymatic activity) is plotted against the mole fractions of these two components. χ A is the mole fraction of compound A and P is the physical property being measured to understand complex formation. This property is most oftentimes UV absorbance.

  5. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    Potassium hexacyanidoferrate(II) is used in a mixture with potassium ferricyanide and phosphate buffered solution to provide a buffer for beta-galactosidase, which is used to cleave X-Gal, giving a bright blue visualization where an antibody (or other molecule), conjugated to Beta-gal, has bonded to its target. On reacting with Fe(3) it gives a ...

    Ferric EDTA can be used as a component for the Hoagland solution or the Long Ashton Nutrient Solution. [7] According to Jacobson (1951), [2] the stability of ferric EDTA was tested by adding 5 ppm iron, as the complex, to Hoagland's solution at various pH values. No loss of iron occurred below pH 6.

    For example, if the reaction equation had 2 H + ions in the product, then the "change" for that cell would be "2x" The fourth row, labeled E, is the sum of the first two rows and shows the final concentrations of each species at equilibrium. It can be seen from the table that, at equilibrium, [H +] = x.
