Solution:
5) NaNO3 solution is working as a salt bridge. A salt bridge is used to establish an electrical contact between two half cells.A salt bridge must be unreactive in nature.
6) No
A salt bridge must be unreactive and posses nearly equal transference number for both cation and anion. Sodium chloride can reacts with the electrolytic solution to form precipitate, hence does not used as salt bridge.
Add Answer to:
5. What was the purpose of the NaNO3 solution in this experiment? 6. Could a solution...
