Electrolysis
Explain the process of electrolysis of molten compounds and aqueous solutions; predict products at each electrode
What you'll learn
- 1
Imagine you have a glass of water with salt dissolved in it. If you put two metal rods in and connect a battery, the salt water starts to fizz and bubbles appear!
- 2
What does electrolysis use to split a liquid?
- 3
Set up the electrolysis cell: drag the wires to connect the battery to the two metal rods.
- 4
Let's see what happens to copper chloride when we electrolyse it.
- 5
Which rod do the copper atoms go to in copper chloride electrolysis?
- 6
Watch the atoms move: drag the copper atoms to the negative rod and the chlorine atoms to the positive rod.
- 7
What is produced at the positive rod when electrolysing copper chloride?
