Electrolysis quiz Loading... 1. Explain whether solid ionic compounds conduct electricitySolid 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 moveSolid ionic compounds sometimes conduct electricity, only when the ions are free to moveQuestion 1 of 11 Loading... 2. Are cations positively or negatively charged?neutralpositively (ca+ions)eithernegativelyQuestion 2 of 11 Loading... 3. What is the formula of aluminium oxide?Al₃OAl₃O₂AlO₃Al₂O₃Question 3 of 11 Loading... 4. When can ionic substances conduct electricity?Only when moltenWhen molten or dissolvedIn any stateNeverQuestion 4 of 11 Loading... 5. 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 5 of 11 Loading... 6. Typically, do covalent substances conduct electricity?YesNoDepends on the substanceDepends on conditions (e.g. pressure, temperature etc.)Question 6 of 11 Loading... 7. Explain why metals are malleableMetals have layers of ions that can slide over each otherMetals have delocalised electrons which are free to moveMetals have strong covalent bonds which require a lot of energy to breakMetals have delocalised protons which can moveQuestion 7 of 11 Loading... 8. State the electron configuration of the aluminium ion2,8,22,8,32,82,8,8Question 8 of 11 Loading... 9. What is the name for the positive electrode?electrodeanodecathodeplatinumQuestion 9 of 11 Loading... 10. Why do covalent compounds (e.g H₂O) not conduct electricity?There are charged particles that are free to moveThere are no charged particles that are free to moveThere is a sea of delocalised electrons that are free to moveThere are weak intermolecular forces that require little energy to breakQuestion 10 of 11 Loading... 11.
