| 11.2 | Halogens as oxidising agents and the hydrogen halides Chlorine pulls electrons from bromide and iodide ions; iodine cannot take them back. | Think-Pair-Share | 6 Q, 14 marks | 8 MCQ | tab 2, tab 3 |
| 11.3 | Reactions of the halide ions Halide ions are reducing agents, and the bigger they are the more readily they hand over electrons. | Mix-Pair-Share | 6 Q, 14 marks | 8 MCQ | tab 5 |
| 11.4 | Chlorine: disproportionation and water treatment In sodium hydroxide, some chlorine atoms gain electrons while others lose them. | Jigsaw | 6 Q, 14 marks | 8 MCQ | tab 4 |
