Abstract

In this article, novel experiments on the topic of redox reactions are presented. These reactions take place in small sodium alginate beads, containing some of the reactants. By immersing the beads in various solutions, the pH-dependence of the redox potentials of some redox systems and different redox states can be visualized by eye.
