#2.15
understand how metals can be arranged in a reactivity series based on their reactions with:
- water
- dilute hydrochloric or sulfuric acid.
#2.16
understand how metals can be arranged in a reactivity series based on their displacement reactions between:
- metals and metal oxides
- metals and aqueous solutions of metal salts.
#2.17
know the order of reactivity of these metals: potassium, sodium, lithium, calcium,magnesium, aluminium, zinc, iron, copper, silver, gold
#2.18
know the conditions under which iron rusts
#2.19
understand how the rusting of iron may be prevented by:
- barrier methods
- galvanising
- sacrificial protection.
#2.20
understand the terms:
- oxidation
- reduction
- redox
- oxidising agent
- reducing agentin terms of gain or loss of oxygen and loss or gain of electrons.
#2.21
practical: investigate reactions between dilute hydrochloric and sulfuric acids and metals (e.g. magnesium, zinc and iron)
