Electrolysis of Aqueous Solutions EXPLAINED | Lecture 3 + MCQs | IGCSE/O Level Chemistry (0620/5070)

Lecture 3 is here - and this is where electrolysis gets TRICKY! Aqueous solutions have competing ions (from water AND the dissolved compound), so predicting products becomes more complex. But don't worry - we break down the rules step-by-step and work through past paper questions so you know exactly what examiners expect. 🔥 What you'll learn: • Why aqueous solutions are different from molten compounds • The reactivity series and discharge rules at the cathode • Predicting which ions get discharged at the anode (halides vs other anions) • How water affects product prediction (H⁺ and OH⁻ ions compete!) • Step-by-step method for ANY aqueous electrolysis question • Past paper question walkthroughs (see how it's actually tested in exams) This is one of the most exam-heavy topics in electrochemistry - master this and you're set for A/A* questions. 📌 Join the ChemFusion WhatsApp Community: https://chat.whatsapp.com/DMeJ4iHyxY7...
