Electrolysis and Covalent bonding 0.0 / 5 ? ChemistryElectrolysisGCSEAQA Created by: Bethany WatsCreated on: 02-11-18 17:09 what state do the substances need to be in for electrolysis ? Why ? molten or dissolved so they can conduct electricity 1 of 11 what does electrolysis require electricity 2 of 11 cation and anion, which one is positive and which one is negative cation is positive anion is negative 3 of 11 what are the rods made out of for electrolyis ? carbon 4 of 11 what kind of current is used for electrolysis ? direct 5 of 11 for electrolysis what is loosed and what is gained? OILRIG oxidation is loosed and reduction is gained 6 of 11 what is the order of discharge at the cathode and anode. Remember at the anode the simplest ion will discharge first for the anode its : chlorine, hydroxide, sulfate. for the cathode its: copper, hydrogen, sodium. 7 of 11 how can you tell the number of outer electrons for covalent bonding? look at the atomic number 8 of 11 why does oxygen have a low boiling point ? it has weak covalent bonds between the oxygen atoms 9 of 11 what is the structure of diamond Carbon atoms) one carbon atom strongly bonded to 4 other carbon atoms 10 of 11 what is a covalent bond when a non-metal shares electrons with a metal to get to a stable state 11 of 11
