Question
Consider the following description os a voltaic cell: A 1.0 M solution of Ni(NO3)2 is placed in a beaker with a strip of nickel metal. A 1.0 M solution of SnSO4, is placed in a second beaker with a strip of Sn metal. The two beakers are connected with a salt bridge and the two metal electrodes are linked by a wire to a voltmeter.
1.What is the voltage generated by the cell at standard conditions?
2.Write a balanced net ionic equation for the overall cell reaction.
3. Write the abbreviated form of the cell notation.
Explanation / Answer
First, write the half-cell reaction for each electrode -in reduction way- with its repective standard reduction potential:
1) Ni2+(aq) + 2e <--> Ni(s), E
