Electrolysis quiz Loading... 1. Explain what is meant by electrolysisThe fusing a substance using electricityThe heating of a substance using electricityThe breakdown of a substance using heatThe breakdown of a substance using electricityQuestion 1 of 11 Loading... 2. Why do covalent compounds (e.g H₂O) not conduct electricity?There are no 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 charged particles that are free to moveQuestion 2 of 11 Loading... 3. How many electrons in a phosphide ion?185n/a (the phosphide ion does not exist)15Question 3 of 11 Loading... 4. Describe the structure of metalsA giant regular 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 electronsA giant random 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 electronsQuestion 4 of 11 Loading... 5. In terms of electrons, what is reduction?Reduction is the conversion of protons to electronsReduction is the sharing of electronsReduction is the loss of electronsReduction is the gain of electronsQuestion 5 of 11 Loading... 6. Do ionic substances conduct electricity?Only when moltenNot when solid, but they do when either molten or in solutionNo, ionic substances never conduct electricityYes, ionic substances always conduct electricityQuestion 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 negative metal ions and a sea of delocalised protonsThere is a strong electrostatic attraction between a regular structure of positive metal ions and a sea of delocalised electronsQuestion 7 of 11 Loading... 8. For what purpose would this equipment be used for in the lab?The electrolysis of a solutionTesting the electrical conductivity of ions in solutionTesting the electrophoresis of a gel melted to liquid stateThe electrolysis of a molten ionic solultionQuestion 8 of 11 Loading... 9. 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 cannot conduct electricity because the ions are not free to 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 moveQuestion 9 of 11 Loading... 10. What are negative ions called?negationsanionscationsprotonsQuestion 10 of 11 Loading... 11. Explain what is meant by electric currentThe rate of flow of elephantsThe rate of flow of ions onlyThe rate of flow of charged particles (e.g. of electrons or ions)The rate of flow of electrons onlyQuestion 11 of 11 Loading...
