A series of precipitations and complex-ion-formations are performed in a single reaction vessel.

The ferric thiocyanate solution is blood red in color, and the intensity of its color is proportional to the amount of complex in solution. The complex is formed according to the reaction: Fe3+ + SCN- ...

Figure 1: Structures of the Fd–FNR complex and PDR. Figure 3: NMR chemical shift perturbation of Fd upon complex formation with FNR. Figure 4: Structural perturbation of FNR induced by complex ...

The data booklet has some examples of complex ion-electron equations. As well as ions and electrons, they involve hydrogen ions (H +) and water (H 2 O). For example, consider permanganate ions (a ...
