摘要：
Im Beitrag werden neu entwickelte Low-Cost-Experimente zur Demonstration der Ionenwanderung im elektrischen Feld pr & auml;sentiert. Als Versuchsgef & auml;ss dient ein Blister aus dem Zeichenbedarf. Die Salze werden zun & auml;chst in Alginatb & auml;llchen eingeschlossen, aus denen sie sukzessive in die umgebende Fl & uuml;ssigkeit diffundieren. Hierzu werden auch Substanzen mit fluoreszierenden Ionen verwendet
