When the voltmeter is removed and the two electrodes are connected by a wire, which of the following does .not. take place?
(A) Negative ions pass through the salt bridge from the silver half-cell to the copper half-cell.
(B) Some positive copper ions pass through the salt bridge from the copper half-cell to the silver half-cell.
(C) The silver electrode increases in mass as the cell operates.
(D) Electrons flow in the external circuit from the copper electrode to the silver electrode.
(E) There is a net general movement of silver ions through the salt bridge to the copper half-cell.
