Electrolysis quiz Loading... 1. Explain what is meant by electrolysisThe heating of a substance using electricityThe fusing a substance using electricityThe breakdown of a substance using electricityThe breakdown of a substance using heatQuestion 1 of 11 Loading... 2. Why do ionic compounds conduct electricity only when molten or in solution?When solid the electrons are held in place. When molten or in solution the electrons are free to moveWhen solid the ions are held in place. When molten or in solution the ions are free to moveWhen solid the ions are free to move. When molten or in solution the ions are held in placeWhen solid the ions are arranged regularly. When molten or in solution the ions are arranged irregularlyQuestion 2 of 11 Loading... 3. 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 3 of 11 Loading... 4. What are negative ions called?anionscationsprotonsnegationsQuestion 4 of 11 Loading... 5. Write ionic half-equations for the reactions at the electrodes in aluminium extractionAl³⁺ + 3e⁻ → Al and 2O²⁻ → O₂ + 4e⁻Al³⁺ → Al + 3e⁻ and 2O²⁻ + 4e⁻ → O₂Al³⁺ + 3e⁻ → Al and 2O²⁻ + 4e⁻ → O₂Al³⁺ → Al + 3e⁻ and 2O²⁻ → O₂ + 4e⁻Question 5 of 11 Loading... 6. 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 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 electronsQuestion 6 of 11 Loading... 7. Why do metals have high melting and boiling points?There is a strong electrostatic attraction between an irregular structure of positive metal ions and a sea of delocalised electronsThere is a weak electrostatic attraction between a regular structure of positive metal ions and a sea of delocalised electronsThere is a strong electrostatic attraction between a regular structure of positive metal ions and a sea of delocalised electronsThere is a strong electrostatic attraction between a regular structure of negative metal ions and a sea of delocalised protonsQuestion 7 of 11 Loading... 8. For what purpose would this equipment be used for in the lab?The electrolysis of a solutionThe electrolysis of a molten ionic solultionTesting the electrophoresis of a gel melted to liquid stateTesting the electrical conductivity of ions in solutionQuestion 8 of 11 Loading... 9. Typically, do covalent substances conduct electricity?YesDepends on the substanceNoDepends on conditions (e.g. pressure, temperature etc.)Question 9 of 11 Loading... 10. State whether covalent substances conduct electricity, and explain whyNo. Because there are no charged particles that are free to moveYes, because there are charged particles that are free to moveOnly under pressure, because there are charged particles that are free to moveOnly when molten, because there are charged particles that are free to moveQuestion 10 of 11 Loading... 11. How many electrons in a neon ion?n/a (Neon is a noble gas so the atom already has a full outer shell of electrons so it does not form ions.)1028Question 11 of 11 Loading...
