# Problem: A 1M solution of Cu ( NO3 )2 is placed in a beaker with a strip of Cu metal. A 1 M solution of SnSO4 is placed in a second beaker with a strip of Sn metal. A salt bridge connects the two beakers, and wires to a voltmeter link the two metal electrodes.Which electrode serves as the anode, and which as the cathode?

###### FREE Expert Solution

We’re being asked to determine which electrode serves as the anode, and which as the cathode for a Cu and Sn galvanic cell.

The half cell reactions for Cu and Sn (these values can be found in textbooks or the internet)

Cu 2+(aq) + 2e- → Cu(s)  E = 0.337 V
Sn 2+ (aq) + 2e- → Sn(s)  E = -0.136 V
