A Strip of Copper Is Placed in a 1 M

question 36

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: 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.
