Electrolysis quiz Loading... 1. For what purpose would this equipment be used for in the lab?The electrolysis of a solutionTesting the electrophoresis of a gel melted to liquid stateThe electrolysis of a molten ionic solultionTesting the electrical conductivity of ions in solutionQuestion 1 of 11 Loading... 2. Explain what is meant by electric currentThe rate of flow of electrons onlyThe rate of flow of charged particles (e.g. of electrons or ions)The rate of flow of ions onlyThe rate of flow of elephantsQuestion 2 of 11 Loading... 3. Explain why metals are malleableMetals have layers of ions that can slide over each otherMetals 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 moveQuestion 3 of 11 Loading... 4. Write an equation to show the formation of the product at the cathode during the electrolysis of copper chloride2Cl⁻ + 2e⁻ → Cl₂ Cu²⁺ → Cu + 2e⁻Cu²⁺ + 2e⁻ → Cu2Cl⁻ → Cl₂ + 2e⁻Question 4 of 11 Loading... 5. 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 5 of 11 Loading... 6. Describe the structure of metalsA simple 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 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 6 of 11 Loading... 7. Why do covalent compounds (e.g H₂O) not conduct electricity?There are charged particles that are free to moveThere are weak intermolecular forces that require little energy to breakThere is a sea of delocalised electrons that are free to moveThere are no charged particles that are free to moveQuestion 7 of 11 Loading... 8. What are negative ions called?protonsnegationscationsanionsQuestion 8 of 11 Loading... 9. During the electrolysis of water, oxygen gas is given off. The formation of this gas can be represented by the ionic equation: ....OH⁻ → ....H₂O + ....O₂ + ....e⁻4OH⁻ → 2H₂O + 2O₂ + 4e⁻4OH⁻ → 2H₂O + O₂ + 2e⁻4OH⁻ → 2H₂O + O₂ + 4e⁻2OH⁻ → 2H₂O + O₂ + 4e⁻Question 9 of 11 Loading... 10.
