Top Tips
- Glass, clay, fertilisers - this is all big-picture stuff, don't get too bogged down in details
- Understand the reasons for the conditions in the Haber process in terms of equilibrium, rate, safety and cost
- Make sure you know your alloys (including their structure and properties from Structure & Bonding in Y10)

📚 Recap
📘 Specification
AQA: Using Materials & Fertilisers
The official Chemistry-only specification covering corrosion,
alloys, ceramics, polymers, composites, the Haber process
and NPK fertilisers.
📘 Cells Specification
AQA: Chemical Cells & Fuel Cells
The official requirements for simple cells, voltage, batteries,
rechargeable cells, hydrogen fuel cells and Higher Tier
electrode half-equations.
🔋 Cells & Batteries
Seneca: Chemical Cells
Review how simple cells produce a potential difference and
how changing electrodes and electrolytes affects the voltage,
with links through to batteries and rechargeable cells.
⚡ Fuel Cells
Seneca: Fuel Cells
Review how fuel cells generate electricity, the role of hydrogen
and oxygen and the advantages and disadvantages of fuel cells
compared with conventional batteries.
🛡️ Corrosion
Seneca: Corrosion
Review the conditions required for rusting and methods used
to prevent corrosion, including barrier methods, galvanising
and sacrificial protection.
🔩 Alloys & Materials
Seneca: Alloys
Review steels, brass, bronze, gold carats and aluminium alloys,
including how alloying changes properties and why particular
alloys are chosen for different uses.
