Short explanation
In the subtopic The process of electrolysis, this learning objective focuses on identify the negative electrode as the cathode. It sits within Electrolysis for AQA GCSE Chemistry 8462 Unit 4.4, so the explanation must stay anchored to chemical changes rather than drifting into a general chemistry idea. Approved keywords to use include electrode, cathode. Electrode. means a conductor through which electricity enters or leaves an electrolyte during electrolysis Avoid the mistake of students often confuse the terms 'anode' and 'cathode', mistakenly identifying the negative electrode as the anode instead of the cathode; instead, remember that the cathode is the negative electrode where reduction occurs, while the anode is the positive electrode where oxidation takes place For exam answers, always identify the negative electrode as the cathode during electrolysis Keep acid, alkali and base distinct; keep oxidation and reduction distinct; do not mix reduction with displacement; keep electrolysis separate from electroplating; distinguish anode from cathode, positive ions from negative ions, oxidation state from ionic charge, and strong acid from concentrated acid.
