What allows electrons to flow between electrodes in an electrochemical cell?A.Salt bridgeB.Electrolyte solutionsC.Conducting wireD.Battery
Solution
In an electrochemical cell, the flow of electrons between electrodes is facilitated by several components:
A. Salt Bridge: This is a U-shaped tube that contains a salt solution. It connects the two half-cells of an electrochemical cell and allows the flow of ions, maintaining electrical neutrality. However, it does not directly allow the flow of electrons.
B. Electrolyte Solutions: These are solutions that contain ions and are present in each half-cell of an electrochemical cell. They facilitate the flow of ions, not electrons.
C. Conducting Wire: This is a crucial component that connects the two electrodes in an electrochemical cell. Electrons flow from the anode (where oxidation occurs) to the cathode (where reduction occurs) through this conducting wire.
D. Battery: This is a device composed of one or more electrochemical cells with external connections. It does not directly allow the flow of electrons between electrodes in a single electrochemical cell.
So, the correct answer is C. Conducting Wire. This is what allows electrons to flow between electrodes in an electrochemical cell.
