Electrolysis quiz Loading... 1. Are anions positively or negatively charged?neutraleitherpositivelynegativelyQuestion 1 of 11 Loading... 2. When can ionic substances conduct electricity?When molten or dissolvedIn any stateOnly when moltenNeverQuestion 2 of 11 Loading... 3. Why do ionic compounds conduct electricity only when molten or in solution?When 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 moveWhen 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 placeQuestion 3 of 11 Loading... 4. 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 4 of 11 Loading... 5. Name the product formed at the cathode during the electrolysis of waterhydrogenoxygenhydroxidechlorineQuestion 5 of 11 Loading... 6. Describe the bonding in a metalThe strong electrostatic attraction between a regular structure of positive ions and a sea of delocalised electronsThe strong electrostatic attraction between oppositely charged ionsThe strong electrostatic attraction between a shared pair of electrons and two nucleiThe strong electrostatic attraction between protons and neutronsQuestion 6 of 11 Loading... 7. Typically, do covalent substances conduct electricity?Depends on conditions (e.g. pressure, temperature etc.)YesDepends on the substanceNoQuestion 7 of 11 Loading... 8. In terms of electrons, what is oxidation?Oxidation is the gain of electronsOxidation is the sharing of electronsOxidation is the gain of oxygenOxidation is the loss of electronsQuestion 8 of 11 Loading... 9.
