Electroplating & industrial electrolysis
Narrated lesson · press play
Electrolysis isn't just a lab curiosity — it plates jewellery with gold, purifies copper, and makes aluminium and chlorine on an industrial scale. Learn how copper electrodes change the reaction, how electroplating works, and how industry uses electrolysis.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 5.1):
- Recall the anode reactions and products of electrolysing copper(II) sulfate with carbon or copper electrodes
- Describe the electroplating of metals and name uses of electroplating
- Outline the manufacture of aluminium from pure aluminium oxide in molten cryolite
- Outline the manufacture of chlorine and sodium hydroxide from concentrated aqueous sodium chloride
