Question
Copper electrodes are placed into two aqueous solutions of copper(II) sulfate at 25 ºC. One compartment contains a 1.0 M solution while the other compartment contains a 0.10 M solution. The two compartments are connected with a salt bridge and the electrodes are connected by a wire passing through a voltmeter. In what direction do the electrons flow through the wire, and what is the cell potential read on the voltmeter?
From the electrode in the 1.0 M solution to the electrode in the 0.10 M solution, 30 mV
From the electrode in the 1.0 M solution to the electrode in the 0.10 M solution, 59 mV
From the electrode in the 0.10 M solution to the electrode in the 1.0 M solution, 30 mV
From the electrode in the 0.10 M solution to the electrode in the 1.0 M solution, 59 mV
