The Reactivity Series
Your loss is my gain
Here we will use broader definition of oxidation and reduction which considers the loss and gain of electrons.
f. Students will be assessed on their ability to:
2.29 understand that metals can be arranged in a reactivity series based on the reactions of the metals and their compounds: potassium, sodium, lithium,calcium, magnesium, aluminium, zinc, iron, copper, silver and gold
2.30 describe how reactions with water and dilute acids can be used to deduce the following order of reactivity: potassium, sodium, lithium, calcium,magnesium, zinc, iron and copper
2.31 deduce the position of a metal within the reactivity series using displacement reactions between metals and their oxides, and between metals and their salts in aqueous solutions
2.32 understand oxidation and reduction as the addition and removal of oxygen respectively
2.33 understand the terms redox, oxidising agent, reducing agent
2.34 describe the conditions under which iron rusts
2.35 describe how the rusting of iron may be prevented by grease, oil, paint,plastic and galvanising
2.36 understand the sacrificial protection of iron in terms of the reactivity series
