Electrolysis quiz Loading... 1. 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 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 irregularlyWhen solid the ions are held in place. When molten or in solution the ions are free to moveQuestion 1 of 11 Loading... 2. Typically, do covalent substances conduct electricity?NoDepends on conditions (e.g. pressure, temperature etc.)Depends on the substanceYesQuestion 2 of 11 Loading... 3. Describe the structure of metalsA giant 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 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 electronsQuestion 3 of 11 Loading... 4. When can ionic substances conduct electricity?Only when moltenIn any stateWhen molten or dissolvedNeverQuestion 4 of 11 Loading... 5. What are positive ions called?cations (ca+ions)electronsanionsprotonsQuestion 5 of 11 Loading... 6. For what purpose would this equipment be used for in the lab?The electrolysis of a molten ionic solultionThe electrolysis of a solutionTesting the electrophoresis of a gel melted to liquid stateTesting the electrical conductivity of ions in solutionQuestion 6 of 11 Loading... 7. What type of reaction takes place at the anode?displacementoxidationprecipitationreductionQuestion 7 of 11 Loading... 8. Why do covalent compounds (e.g H₂O) not conduct electricity?There is a sea of delocalised electrons that are free to moveThere are weak intermolecular forces that require little energy to breakThere are no charged particles that are free to moveThere are charged particles that are free to moveQuestion 8 of 11 Loading... 9.
