Edexcel IGCSE Chemistry Lecture 19 - Metals and the Reactivity Series

Powerpoint lecture covering the following in a modern, concise format:

Specification Point 2.15 - Understand how metals can be arranged in a reactivity series based on their reactions with water or dilute acid.

Specification Point 2.16 - Understand how metals can be arranged in a reactivity series based on displacement reactions.

Specification Point 2.17 - Know the order of reactivity of these metals: potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, copper, silver, and gold.

Specification Point 2.18 - Know the conditions under which iron rusts.

Specification Point 2.19 - Understand how the rusting of iron may be prevented by barrier methods, galvanising and sacrificial protection.

Specification Point 2.20 - Understand the terms oxidation, reduction, redox, oxidising agent and reducing agent in terms of the gain or loss of oxygen and the loss or gain of electrons.

Specification Point 2.21 - Practical: investigate reactions between dilute hydrochloric and sulfuric acids and metals (e.g. magnesium, zinc and iron).
