Demonstration

Electrolysis of molten zinc chloride

In association with Nuffield Foundation

Try this demonstration to show how an ionic salt will conduct electricity when molten but not when solid. Includes kit list, video and safety instructions.

Resource

Hand battery

In association with The Solar Spark at the University of Edinburgh

Complete a circuit by placing your hands on two metal plate electrodes.

Class experiment

Exothermic redox reaction of zinc with iodine

In association with Nuffield Foundation

Using an exothermic redox reaction between zinc and iodine, student will make zinc iodide. This can be reversed using electrolysis to decompose the compound.

On This Day - May 02: Nicholson split water

The English chemist discovered that when leads from a battery are placed in water (H₂O), the water breaks up into hydrogen (H₂) and oxygen (O₂) bubbles, which collect separately at the submerged ends of the wires. This process is called electrolysis.

On This Day – Sep 02 : Friedrich Ostwald was born

He was one of the founders of classical physical chemistry. In particular, Ostwald was a pioneer of electrochemistry and chemical dynamics. He won the Nobel Prize for Chemistry in 1909 for his work on catalysis, chemical equilibrium, and reaction velocities.
