Switch KNO, Salt Bridge Cu Sn 1.0 M Cu(NO,), 1.0 M Sn(NO,)2 The voltaic cell pictured above is constructed with electrodes of known mass. The switch is closed and the cell is allowed to operate for a period of time. At that point, the electrodes were rinsed, dried, and massed and it was discovered that the copper metal had a higher mass than it initially had. a) Which metal is the anode? b) Which metal is the cathode? c) Write the half equation for the process that occurs at the anode.
