Question

(a) A constructed voltaic cell is shown below,

i) Write the overall equation for the cell
ii) Write the cell notation
iii) Determine the cell voltage of this voltaic
cell

(b) An electrochemical cell is set up from a Ag+/Ag half-cell and a Ni2+/Ni half-cell. The concentration of the nickel ions is 1.2 mol dm-3
in the Ni2+/Ni half-cell. Calculate the concentration of the silver ions in the Ag+/Ag half cell if the cell voltage of the electrochemical cell obtained at 25oC is 0.98V.
[Eo Ag+/Ag =+0.80 V , Eo Ni2+/Ni = -0.25V]
