Video and resources investigating the displacement reactions between the halogens chlorine, bromine and iodine and their respective halides in microscale

Learn about the displacement reactions between halogen ions and their respective halides with this microscale version of the experiment. Use the results of these reactions to explain the reactivity trend of the halogens for GCSE and equivalent 14–16 courses. Additional resources including pause-and-think questions with answers, teacher notes, technician notes, integrated instructions, intended outcomes, follow-up worksheet and structure strips are provided to support your teaching.
