Question

Which component of an electrochemical cell is correctly paired with its function?(1) external conductor – allows ions to flow(2) external conductor – permits electrons to flow(3) salt bridge – allows the solutions to mix(4) salt bridge – permits electrons to flow

Answer 1

Electrochemical cells are devices in which the transfer of electrons occurs through an external circuit instead of occurring directly between the reactants; in this way the flow of electrons (electric current) can be used.

The salt bridge allows the transfer of ions, and the electrons flow through the external circuit, therefore the answer will be:

Answer: (2) external conductor – permits electrons to flow
