The reactivity series
- Metals can be put into an order of reactivity
- Potassium, Sodium, lithium, calcium, magnesium,
aluminium, zinc, iron,tin,lead,copper, silver, gold,
platinium
- For reactions see printed sheet
- Potassium, Sodium, lithium, calcium, magnesium,
aluminium, zinc, iron,tin,lead,copper, silver, gold,
platinium
- In a displacement reaction, a MORE
REACTIVE metal replaces a LESS
reactive metal.
- Oxidation - Addition of oxygen
- Reduction - Removal of oxygen
- Redox - Reduction at the cathode and oxidation at the annode
- Oxidising agent - Something that causes oxidation
- Reducing agent - Something that causes a reduction
- Rusting
- An oxidation reaction
- On the corrosion of IRON
- Needs oxygen and water present
- The iron gains oxygen and forms iron (III)
oxide and then water bonds to it to form
hydrated iron (III) oxide, rust.
- Can be prevented by: Grease,
oil, paint, plastic and galvonsing
- An oxidation reaction
