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.What is the emf generated by the cell under standard conditions?

FREE Expert Solution

We're asked to determine the emf generated by the cell under standard conditions


The cell contains 1 M solution of Cu(NO3)2 placed in a beaker with a strip of Cu metal with a salt bridge connecting to a 1 M solution of SnSO4 placed in a second beaker with a strip of Sn metal


Recall that E°cell  is the emf under standard conditions given by the equation:


E°cell=E°cathode-E°anode


We can calculate for the standard emf, E°cell  using the following steps:
