A voltaic cell is constructed from
an Ni2+(aq)−Ni(s) half-cell and
an Ag+(aq)−Ag(s) half-cell.
The initial concentration of Ni2+(aq) in the Ni2+−Ni half-cell is [Ni2+]= 1.00×10−2 M . The initial cell voltage is +1.12 V .

a. By using data in Table 20.1 in the textbook, calculate the standard emf of this voltaic cell.

b. Will the concentration of Ni2+(aq) increase or decrease as the cell operates?

c. What is the initial concentration of Ag+(aq) in the Ag+−Ag half-cell?
