Abstract
Singularity theory of a distinguished parameter has been applied to a kinetic model of zinc electrodeposition to map out the regions on the [Zn2+]‐pH plane having different types of bifurcation diagrams. The bifurcation diagrams show the dependency of the state variable, the fractional surface coverage of a zinc intermediate , on the electrode potential under steady‐state conditions. The analysis shows that the system can exhibit as many as 23 different types of steady‐state responses depending upon the pH and [Zn2+], many of which occur over small parameter ranges and differ subtly from one another. The power of singularity theory is well illustrated by the fact that only by its application can all of these regions be identified in a straightforward and systematic manner.
