16. In which direction do electrons flow in an electrochemical cell? a From the cathode to the anode through the salt bridge b. From the cathode to the anode through the external circuit. c. From the anode to the cathode through the salt bridge. d. From the anode to the cathode through the external circuit. 17. A galvanic cell is made up of two half-cells connected by an external conductor and a porous salt bridge. Which of the following best explains the function of the salt bridge in a galvanic cell? a. It permits the migration of salt bridge ions into the electrolyte solutions, thus maintaining neutrality. b. It prevents migration of electrolytes from both the anode and cathode electrodes, thus maintaining neutrality. C. It permits the flow of electrons by allowing the two separate electrochemical cells connect; thus, neutrality is maintained. d. It prevents the mixing of electrolytes from both the anode and cathode electrodes: thus, neutrality is maintained.
