By , 
Ian Davies and 
Sandrine Bouchelkia
Video and supporting resources investigating electrolysis of aqueous solutions.
Investigate electrolysis of aqueous solutions with this simple experiment for learners to explore the concept for GCSE and equivalent 14-16 courses. The video uses copper sulfate as the example and the supporting resources introduce other aqueous solutions, sodium chloride and hydrochloric acid. 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.
Chapter titles: 00:09 Introduction; 00:56 Experiment set up; 02:54 The negative electrode; 03:48 The positive electrode; 04:44 Oxidation and reduction
