AQA GCSE chemistry - Unit 4 - Lesson 8-10 Electrolysis, extraction, plating, half equations

This is a sequence of lessons to teach the topic of electrolysis. It contains three powerpoint presentations, a worksheet on ionic and half equations and the worksheets for the required practical on electrolysis. It could cover three lessons of teaching with another 2 to complete the required practical and so is resourced for 5 lessons in total.

Lesson 1
Powerpoint 1

1. The process of electrolysis
2. REDOX and loss and gain of electrons
3. Electrolysis of molten ionic compounds

Lesson 2
Powerpoint 2

1. Using electrolysis to extract metals
2. Electrolysis of aluminium oxide
3. Electroplating with copper
4. Half equations and Ionic Equations

Set homework: worksheet on ionic and half equations to be completed for homework here - mark scheme provided

Lesson 3
Required Practical 3

Lesson 4
Completion of booklet for required practical 3

Lesson 5
Powerpoint 3

1. Electrolysis in aqueous solution
2. Mixtures of ions
3. Electrolysis of brine
4. Competing reactions at electrodes
5. Electrolysis of acidified water

I write Professor Bunsen resources to teach and test in my own classroom. I hope that I manage to make the new GCSE in chemistry engaging and exciting. Most importantly it could save you and your school time!
