WebElectrolysis is the decomposition of a compound using electricity: The decomposition of molten lead bromide occurs using the apparatus above. A current is passed through graphite rods called electrodes. The negative terminal is attached to one rod, which becomes the negative electrode, the cathode. The positive terminal is attached to the … WebDefinition. Half equations. Term. What happens at the cathode in electrolysis? Definition. Electrons arrive at the cathode (negative electrode) from the power suppluy, this gives it a negative charge and so attracts the cations (positive ions), the cations then take up the electrons to form atoms (not ions) This is a form of a reduction reaction.
WebKidzSearch Safe Wikipedia for Kids. Electrolysis is a scientific way of 'splitting' substances. Electrolysis means 'electric-splitting' and involves the separation of substances through an electric current. Metals above carbon in the reactivity series ( potassium, sodium, lithium, calcium, magnesium and aluminium) are extracted by electrolysis. WebElectrolysis can be one of the trickiest subject areas that students will come across in their GCSE Chemistry course. For parents, the best way to support your child is to break …
