Electrolysis quiz Please wait... 1. Why do metals have high melting and boiling points?There is a strong electrostatic attraction between a regular structure of positive metal ions and a sea of delocalised electronsThere 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 protons Loading... Question 1 of 11 2. 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 move Loading... Question 2 of 11 3. For what purpose would this equipment be used for in the lab?The electrolysis of a solutionThe electrolysis of a molten ionic solultionTesting the electrophoresis of a gel melted to liquid stateTesting the electrical conductivity of ions in solution Loading... Question 3 of 11 4. Why do covalent compounds (e.g H₂O) not conduct electricity?There are no charged particles that are free to moveThere are charged particles that are free to moveThere is a sea of delocalised electrons that are free to moveThere are weak intermolecular forces that require little energy to break Loading...
