AQA A-Level Chemistry - The Halogens (Gp. 7)

This video runs through the halogens section of the AQA spec. Note that it does not cover the trends in boiling point and electronegativity.
Due to the length of the video, the following markers can be used to take you to the named sections:
3:57 - displacement (oxidising power of the halogens)
13:43 - formation of bleach
16:26 - chlorine and water
20:22 - halides as reducing agents
23:23 - reactions with sulphuric acid
34:19 - testing for halides
