A short video/audio guide covering the basics of electrolysis: electricity can decompose ionic compounds into elements; useful elements in brine, e.g. chlorine for PVC; negative ions give up electrons at the anode, positive ions take up electrons at the cathode; half equations of oxidation/reduction; chlorine and hydrogen molecules are discharged as gases; remaining solution is NaOH, a useful industrial substance.
