A Landolt pH-oscillator based on a bromate/sulfite/ferrocyanide reaction has been developed with a room temperature period of 20 minutes and a range of 3.1periodic oscillations in volume in a pH responsive hydrogel. A continuously stirred, constant volume, tank reactor was set-up in conjuction with a modified JKR experiment and is used to show that the combination of a pH oscillator and a pH responsive hydrogel can be used to generate measurable force.

Haleys Dialyzed Iron and Related Methods, Hyaluronic acid was said by Hale to combine with dialyzed iron in acetic acid solution 89), After the sections were rinsed, the classical HCl - potassium ferrocyanide reaction was used to color (as Prussian blue) the sites of iron-binding. The need for fixatives that would not dissolve hyaluronic acid was emphasized. The specificity was established by exposing duplicate portions of tissue to streptococcal hyaluronidase, presumable filtrates, before staining. This prevented coloration of hyaluronic acid but not that of other acidic carbohydrates. 

Magnesium behaves analogously to calcium, but strontium is not precipitated from concentrated solutions. Thus the ferrocyanide reaction can be used to test for calcium in the alkaline earth group. 

A set of equivalent polarization curves of the ferri/ferrocyanide reaction is used as the experimental data, which is the input to the model methodology. As advised in (Tourwe et al., 2006), 11 voltammograms are measured under identical conditions for every rotation speed. The resulting voltammograms for the Ee(CN) /Fe(CN) system are shown in Figure 3. 

The analytical expression is derived for the reduction/oxidation of ferri/ferrocyanide (reaction (23)). The basic equations that describe this mechanism, when studied under... 

The application of the analytical modeling for the study of the ferri/ferrocyanide reaction with LSV/RDE experiments demonstrate that the modeling methodology is valid to extract the quantitative mechanism of an electrochemical reaction. In the case of the hexaammineruthenium (III)/(II) reaction, however, the results of the analytical modeling point out the importance of a correct formulation of the reaction mechanism.
