Electrolysis quiz Loading... 1. Do ionic substances conduct electricity?Not when solid, but they do when either molten or in solutionOnly when moltenYes, ionic substances always conduct electricityNo, ionic substances never conduct electricityQuestion 1 of 11 Loading... 2. How many electrons in an aluminum ion?1018n/a (Aluminium does not form ions)13Question 2 of 11 Loading... 3. Typically, do covalent substances conduct electricity?Depends on the substanceYesDepends on conditions (e.g. pressure, temperature etc.)NoQuestion 3 of 11 Loading... 4. Are anions positively or negatively charged?eitherneutralpositivelynegativelyQuestion 4 of 11 Loading... 5. Explain why metals are malleableMetals have strong covalent bonds which require a lot of energy to breakMetals have delocalised protons which can moveMetals have delocalised electrons which are free to moveMetals have layers of ions that can slide over each otherQuestion 5 of 11 Loading... 6. Explain whether solid ionic compounds conduct electricitySolid ionic compounds sometimes conduct electricity, only when the ions are free to moveSolid ionic compounds can conduct electricity because the ions are free to moveSolid ionic compounds can conduct electricity because there is a sea of delocalised electrons that can moveSolid ionic compounds cannot conduct electricity because the ions are not free to moveQuestion 6 of 11 Loading... 7. State whether covalent substances conduct electricity, and explain whyNo. Because there are no charged particles that are free to moveOnly under pressure, because there are charged particles that are free to moveYes, because there are charged particles that are free to moveOnly when molten, because there are charged particles that are free to moveQuestion 7 of 11 Loading... 8. In the electrolysis of molten aluminium oxide, write the name and formula of the particles which move to the positive electrodealuminium ions (Al²⁺)oxygen ions (O⁻)aluminium ions (Al³⁺)oxide ions (O²⁻)Question 8 of 11 Loading... 9. Describe the structure of metalsA simple regular structure of positive metal ions surrounded by a sea of delocalised electronsA simple random structure of positive metal ions surrounded by a sea of delocalised electronsA giant random structure of positive metal ions surrounded by a sea of delocalised electronsA giant regular structure of positive metal ions surrounded by a sea of delocalised electronsQuestion 9 of 11 Loading... 10. For what purpose would this equipment be used for in the lab?Testing the electrical conductivity of ions in solutionThe electrolysis of a solutionTesting the electrophoresis of a gel melted to liquid stateThe electrolysis of a molten ionic solultionQuestion 10 of 11 Loading... 11.
