ChemistryElectrolysisGCSEAQA Created by: MariCreated on: 16-03-13 17:03 Molten Reduced to liquid from by heating. 1 of 9 Ionic Substance When a metal reacts with a non metal. 2 of 9 Ions Electrically charged particles, formed when an atom or molecule gains or loses electrons. 3 of 9 Oxidation Gaining of oxygen and LOSS of electrons. 4 of 9 Reduction Loss of oxygen and GAIN of electrons. 5 of 9 Negative Electrode (cathode) Positive ions are attracted to the negative electrode during electrolysis. Here they gain electrons (reduction). 6 of 9 Positve Electrode (anode) Negative ions are attracted to the positive electrode during electrolysis. Here they lose electrons (oxidation). 7 of 9 O I L R I G Oxidation Is Loss Reduction Is Gain 8 of 9 Electrolysis The process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. 9 of 9
