C11 Syllabus Statements

Air and water from Carole Paquette – this powerpoint covers most of what you need to know (it just misses out some of the effects of carbon dioxide as a pollutant).



Complete Chemistry for Cambridge IGCSE, chapter 15, pp.210 – 219 & chapter 16, pp.226 – 228, pp.234 – 235 & 238 – 239 (and p.124 for water tests)

Here are some key terms for this topic: Key Terms C11

Air & Pollution

IGCSE Chemistry topic 11, part 2 – Air:

Traffic Pollution is a 3m 14s vid from BBC iScience. Science Bank 1 (Raw Materials): nitrogen & the distillation of liquid air can be found from 8m 31s to 10m 40s and BBC Short Circuit Changes in Atmosphere is a 19m video covering global warming.

Haber Process & Ammonia

A short video form The Virtual School – what are fertilisers?:

The Virtual School explains the Haber process:

IGCSE Chemistry topic 11, part 4 – Haber-Bosch process:

An 8m vid about nitrogen & the Haber process – Useful Products from the Air (GCSE BBC Science Bitesize). Also Science Bank 11 (Industrial Chemistry): part 1 covers ammonia & fertilisers (to 4m 45s) and BBC Short Circuit Ammonia is a 19m video covering the same subject. Fritz Haber: Great Minds (a 9m 40s video from Hank Green).

GCSE Bitesize also covers Reversible Reactions in a 4m 48s video.

This powerpoint covers the Contact Process before the Haber Process (and then alloys):

GCSE s-cool – Reversible Reactions: the Haber process – revision notes

For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ‘9. Reversible Reactions, Equilibrium, Ammonia Manufacture & Uses’. 

Great resources from the Australian International School – videos, powerpoints, worksheets, practicals, animations, flashcards etc.
