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+]= 1.10×10-2 M. The initial cell voltage is +1.13 V.
Calculate the standard emf of this voltaic cell.
Will the concentration of Ni2+(aq) increase or decrease as the cell operates?
What is the initial concentration of Ag+(aq) in the Ag+-Ag half-cell?
