Electrolysis quiz Loading... 1. Do ionic substances conduct electricity?No, ionic substances never conduct electricityOnly when moltenYes, ionic substances always conduct electricityNot when solid, but they do when either molten or in solutionQuestion 1 of 11 Loading... 2. How could you determine if a liquid is an electrolyte?Add two electrodes to the solution. If the solution heats up, it is an electrolytePut it in a circuit including a bulb. If the bulb lights then the liquid is an electrolyteAdd two electrodes to the solution, if a gas is produced at an electrode, the liquid is an electrolyteTest the liquid with universal indicator. If the solution is acidic, it is an electrolyteQuestion 2 of 11 Loading... 3. What does the word malleable mean?Will break or crack under pressureAble to carry currentAble to be hammered or pressed into shape without breaking or crackingAble to be drawn into a wireQuestion 3 of 11 Loading... 4. Explain whether solid ionic compounds conduct electricitySolid 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 moveSolid ionic compounds can conduct electricity because the ions are free to moveQuestion 4 of 11 Loading... 5. 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 5 of 11 Loading... 6. How many electrons in a chloride ion?n/a (Chlorine atoms do not form ions)101817Question 6 of 11 Loading... 7. A substance is found not to conduct electricity even when molten. What type of bonding does the substance have?IonicCovalentMetallicCovalent or ionicQuestion 7 of 11 Loading... 8. State whether covalent substances conduct electricity, and explain whyOnly when molten, because there are charged particles that are free to moveOnly under pressure, because there are charged particles that are free to moveYes, because there are charged particles that are free to moveNo. Because there are no charged particles that are free to moveQuestion 8 of 11 Loading... 9. What are positive ions called?protonsanionscations (ca+ions)electronsQuestion 9 of 11 Loading... 10. Write an equation to show the formation of the product at the anode during the electrolysis of copper chloride2Cl⁻ + 2e⁻ → Cl₂ 2Cl⁻ → Cl₂ + 2e⁻Cu²⁺ + 2e⁻ → CuCu²⁺ → Cu + 2e⁻Question 10 of 11 Loading... 11. Describe the bonding in a metalThe strong electrostatic attraction between oppositely charged ionsThe strong electrostatic attraction between protons and neutronsThe strong electrostatic attraction between a shared pair of electrons and two nucleiThe strong electrostatic attraction between a regular structure of positive ions and a sea of delocalised electronsQuestion 11 of 11 Loading...
