Electrochemistry

This section contains a range of practical experiments involving electrochemical cells and electrolysis.

While we are still at an early stage with this website it's probably more useful to look at the page with our complete list of experiments in alphabetical order. See the list on About this website.

We are starting with GCSE-level experiments.

Experiments

• Turning copper coins into 'silver' and 'gold'

  A copper coin is plated with zinc and appears silver in colour. Heating the zinc plated coin forms a coating of brass, and the coin appears gold in colour.

• Rechargeable commercial cells: the lead-acid accumulator

  A simple cell lead-acid cell is constructed and charged and discharged for varying lengths of time.

• Colourful electrolysis

  The electrolysis of salt (sodium chloride) solution performed in a U-shaped test tube with universal indicator.

• Electrolysis of zinc chloride

  Demonstration showing that an ionic compound will not conduct electricity when solid, but will do so when molten.

• Anodising aluminium

  An experiment showing a useful application of electrolysis.
