Electrolysis – OCR Gateway – Revision 3 – GCSE Chemistry Learn about electrolysis and electrolytes with Bitesize GCSE Chemistry (OCR Gateway). uses electrolysis to put a thin layer of a metal onto a metal object. The electrodes used in electroplating are non-inert – they do take part in the electrolysis reactions.
Electrolysis of copper(II) sulfate solution- Learn Chemistry 2019/9/18· With carbon (graphite) electrodes, the oxygen usually reacts with the anode to form CO 2. If copper is used for the electrodes, the copper anode dissolves. The reaction is the reverse of the cathode reaction. The results of this experiment can lead to a discussion
Giant covalent molecules – AQA – Revision 2 – GCSE 2019/9/14· This makes graphite useful for electrodes in batteries and for electrolysis. The forces between the layers in graphite are weak. This means that the layers can slide over each other. This makes graphite slippery, so it is useful as a
