6.4 Redox Past Paper Questions — IGCSE Chemistry 0620 | Worked Solutions

In this video I work through real Cambridge IGCSE Chemistry (0620) past paper questions on redox, topic 6.4, step by step, showing exactly how to phrase answers the way the mark scheme wants. We go through typical exam questions: identifying what's oxidised and what's reduced, explaining answers in terms of electron transfer (and oxidation numbers), spotting oxidising and reducing agents, using colour changes as evidence of redox, and the exact wording examiners award marks for. I'll flag the common mistakes that lose easy marks and how to avoid them. New to this topic? Watch the concept video first: [link to your 6.4 redox concept video].
