IGCSE Chemistry Edexcel 4CH1

understand how metals can be arranged in a reactivity series based on their reactions with:

• water
• dilute hydrochloric or sulfuric acid.

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.

know the order of reactivity of these metals: potassium, sodium, lithium, calcium,magnesium, aluminium, zinc, iron, copper, silver, gold

know the conditions under which iron rusts

understand how the rusting of iron may be prevented by:

• barrier methods
• galvanising
• sacrificial protection.

understand the terms:

• oxidation
• reduction
• redox
• oxidising agent
• reducing agentin terms of gain or loss of oxygen and loss or gain of electrons.

practical: investigate reactions between dilute hydrochloric and sulfuric acids and metals (e.g. magnesium, zinc and iron)
