Electrolysis quiz Loading... 1. Do ionic substances conduct electricity?Yes, ionic substances always conduct electricityNo, ionic substances never conduct electricityNot when solid, but they do when either molten or in solutionOnly when moltenQuestion 1 of 11 Loading... 2. For what purpose would this equipment be used for in the lab?Testing the electrical conductivity of ions in solutionTesting the electrophoresis of a gel melted to liquid stateThe electrolysis of a solutionThe electrolysis of a molten ionic solultionQuestion 2 of 11 Loading... 3. Describe the structure of metalsA giant 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 simple regular structure of positive metal ions surrounded by a sea of delocalised electronsQuestion 3 of 11 Loading... 4. Zinc phosphide, Zn₃P₂ is an ionic compound. The formula of the zinc ion is Zn²⁺. Deduce the formula of the phosphide ionP³⁻P²⁺P³⁺P²⁻Question 4 of 11 Loading... 5. Explain whether solid ionic compounds conduct electricitySolid ionic compounds can conduct electricity because there is a sea of delocalised electrons that can moveSolid ionic compounds can conduct electricity because the ions are free to moveSolid ionic compounds sometimes conduct electricity, only when the ions are free to moveSolid ionic compounds cannot conduct electricity because the ions are not free to moveQuestion 5 of 11 Loading... 6. State whether covalent substances conduct electricity, and explain whyNo. Because there are no charged particles that are free to moveOnly when molten, because there are 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 moveQuestion 6 of 11 Loading... 7. In the electrolysis of molten aluminium oxide, write the name and formula of the particles which move to the negative electrodeoxygen ions (O⁻)oxide ions (O²⁻)aluminium ions (Al²⁺)aluminium ions (Al³⁺)Question 7 of 11 Loading... 8. Explain what is meant by electric currentThe rate of flow of ions onlyThe rate of flow of electrons onlyThe rate of flow of charged particles (e.g. of electrons or ions)The rate of flow of elephantsQuestion 8 of 11 Loading... 9. Why does this equation represent a reduction reaction? Al³⁺ + 3e⁻ → Al Al³⁺ gains electronsAl³⁺ loses oxygenAl³⁺ loses electronsAl³⁺ gains oxygenQuestion 9 of 11 Loading... 10. Explain why metals are good conductors of electricityMetals have delocalised protons which can moveMetals have positive ions which can moveMetals have delocalised electrons which are free to moveMetals have layers of ions that can slide over each otherQuestion 10 of 11 Loading... 11.
