Electrolysis quiz Loading... 1. Name the product formed at the anode during the electrolysis of molten copper chloridechloridecopperchlorinecopper oxideQuestion 1 of 11 Loading... 2. Why do covalent compounds (e.g H₂O) not conduct electricity?There are charged particles that are free to moveThere is a sea of delocalised electrons that are free to moveThere are no charged particles that are free to moveThere are weak intermolecular forces that require little energy to breakQuestion 2 of 11 Loading... 3. Are cations positively or negatively charged?positively (ca+ions)eitherneutralnegativelyQuestion 3 of 11 Loading... 4. Explain what is meant by electric currentThe rate of flow of charged particles (e.g. of electrons or ions)The rate of flow of electrons onlyThe rate of flow of ions onlyThe rate of flow of elephantsQuestion 4 of 11 Loading... 5. Write ionic half-equations for the reactions at the electrodes in aluminium extractionAl³⁺ → Al + 3e⁻ and 2O²⁻ → O₂ + 4e⁻Al³⁺ → Al + 3e⁻ and 2O²⁻ + 4e⁻ → O₂Al³⁺ + 3e⁻ → Al and 2O²⁻ → O₂ + 4e⁻Al³⁺ + 3e⁻ → Al and 2O²⁻ + 4e⁻ → O₂Question 5 of 11 Loading... 6. For what purpose would this equipment be used for in the lab?Testing the electrical conductivity of ions in solutionThe electrolysis of a molten ionic solultionThe electrolysis of a solutionTesting the electrophoresis of a gel melted to liquid stateQuestion 6 of 11 Loading... 7. What is the formula of the fluoride ion?F¹⁻F²⁻F⁷⁺F¹⁺Question 7 of 11 Loading... 8. Explain whether solid ionic compounds conduct electricitySolid ionic compounds can conduct electricity because the ions are free to 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 moveSolid ionic compounds can conduct electricity because there is a sea of delocalised electrons that can moveQuestion 8 of 11 Loading... 9. Do ionic substances conduct electricity?Not when solid, but they do when either molten or in solutionOnly when moltenNo, ionic substances never conduct electricityYes, ionic substances always conduct electricityQuestion 9 of 11 Loading... 10. Describe the bonding in a metalThe strong electrostatic attraction between a regular structure of positive ions and a sea of delocalised electronsThe strong electrostatic attraction between protons and neutronsThe strong electrostatic attraction between oppositely charged ionsThe strong electrostatic attraction between a shared pair of electrons and two nucleiQuestion 10 of 11 Loading... 11.
