|(d) Reactivity series
|2.15 understand how metals can be arranged in a reactivity series based on their reactions with water
and with 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
- sacrificial protection
|2.20 in terms of gain or loss of oxygen and loss or gain of electrons, understand the terms:
- oxidising agent
- reducing agent
|2.21 know how to investigate reactions between dilute hydrochloric and sulfuric acids and metals (e.g. magnesium, zinc and iron)
