Electrolysis quiz Loading... 1. What is the name for the negative electrode?cathodeanodeplatinumelectrodeQuestion 1 of 11 Loading... 2. Do ionic substances conduct electricity?Not when solid, but they do when either molten or in solutionYes, ionic substances always conduct electricityNo, ionic substances never conduct electricityOnly when moltenQuestion 2 of 11 Loading... 3. For what purpose would this equipment be used for in the lab?Testing the electrical conductivity of ions in solutionTesting the electrophoresis of a gel melted to liquid stateThe electrolysis of a solutionThe electrolysis of a molten ionic solultionQuestion 3 of 11 Loading... 4. 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 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 ions are free to move. When molten or in solution the ions are held in placeQuestion 4 of 11 Loading... 5. How many electrons in a sodium ion?81018n/a (Sodium does not form ions)Question 5 of 11 Loading... 6. Typically, do covalent substances conduct electricity?YesDepends on conditions (e.g. pressure, temperature etc.)Depends on the substanceNoQuestion 6 of 11 Loading... 7. Are anions positively or negatively charged?negativelypositivelyeitherneutralQuestion 7 of 11 Loading... 8. State whether covalent substances conduct electricity, and explain whyYes, because there are charged particles that are free to moveNo. Because there are no charged particles that are free to moveOnly when molten, because there are charged particles that are free to moveOnly under pressure, because there are charged particles that are free to moveQuestion 8 of 11 Loading... 9. When chlorine gas is bubbled into an aqueous solution of potassium iodide, the colourless solution turns brown. Complete the following ionic equation: Cl₂(g)+ ___I⁻(aq) → 2Cl⁻(aq) + ___(aq)Cl₂(g) + I⁻(aq) → 2Cl⁻(aq) + I(aq)Cl₂(g) + 2I⁻(aq) → 2Cl⁻(aq) + 2ICl(aq)Cl₂(g) + 2I⁻(aq) → 2Cl⁻(aq) + I₂(aq)Cl₂(g) + 2I⁻(aq) → 2Cl⁻(aq) + 2I(aq)Question 9 of 11 Loading... 10. Describe the bonding in a metalThe strong electrostatic attraction between protons and neutronsThe 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 nucleiQuestion 10 of 11 Loading... 11. Explain why metals are good conductors of electricityMetals have positive ions which can moveMetals have delocalised protons which can moveMetals have layers of ions that can slide over each otherMetals have delocalised electrons which are free to moveQuestion 11 of 11 Loading...
