Elektrochemie
Die Elektrochemie befaßt sich mit dem Zusammenspiel von elektrischen und chemischen Vorgängen, den Redoxreaktionen, bei denen der elektrische Strom beteiligt ist (Elektronenübertragungsreaktion). Dabei finden Umwandlungen von chemischer in elektrische Energie und umgekehrt statt. Die Umwandlung elektrischer in chemische Energie (endothermer Prozess) geschieht bei der Elektrolyse, während bei der Umwandlung chemischer Energie in elektrische exotherme Redoxreaktionen ablaufen. Unsere Experimentiersets zur Elektrochemie eignen sich für Schüler und Studenten. Die Zitronenuhr (Lemon Clock) demonstriert, wie mit einer Zitrone und zwei Kupfer- und Zinkelektroden ganz einfach Strom erzeugt werden kann und eine Digitaluhr betrieben wird. Mit dem Elektrolyseset lassen sich Gegenstände galvanisch verkupfern und der Batterie Bausatz erzeugt aus Metallplatten und Elektrolyt elektrische Spannung.
