A Strip of Copper Is Placed in a 1 M

Question 17

Multiple Choice

A strip of copper is placed in a 1 M solution of copper nitrate, and a strip of silver is placed in a 1 M solution of silver nitrate. The two metal strips are connected to a voltmeter by wires, and a salt bridge connects the solutions. The following standard reduction potentials apply: A strip of copper is placed in a 1 M solution of copper nitrate, and a strip of silver is placed in a 1 M solution of silver nitrate. The two metal strips are connected to a voltmeter by wires, and a salt bridge connects the solutions. The following standard reduction potentials apply:   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)  The silver electrode increases in mass as the cell operates. C)  Electrons flow in the external circuit from the copper electrode to the silver electrode. D)  Some positive copper ions pass through the salt bridge from the copper half-cell to the silver half-cell. E)  There is a net general movement of silver ions through the salt bridge to the copper half-cell.
