64. An electrochemical cell consists of a chromium electrode in 1.0 mol/L solution of Cr(NO3)3 (chromium nitrate), a silver electrode in 1.0 mol/L solution of AgNO3 (silver nitrate) and a salt bridge. The spontaneous cell reaction is + 3Ag* (28) Cr(s) + (aq) + 3Ag (3) When the two electrodes are connected by a wire, which of the following does not take place? a. the silver electrode increases in mass as the cell operates b. negative ions pass through the salt bridge from the silver half-cell to the chromium half- cell some positive chromium ions pass through the salt bridge from the chromium half-cell to the silver half-cell → Cr³+ C. d. the chromium electrode decreases in mass as the cell operates e. electrons flow in the external circuit from the silver electrode to the chromium electrode

Question
Kindly provide me with the solution for the following question:
![64. An electrochemical cell consists of a chromium electrode in 1.0 mol/L solution of Cr(NO3)3 (chromium
nitrate), a silver electrode in 1.0 mol/L solution of AgNO3 (silver nitrate) and a salt bridge. The spontaneous
cell reaction is
Cr(s) + 3Ag* (29)
(aq) + 3Ag(s)
When the two electrodes are connected by a wire, which of the following does not take place?
the silver electrode increases in mass as the cell operates
a.
b. negative ions pass through the salt bridge from the silver half-cell to the chromium half-
cell
some positive chromium ions pass through the salt bridge from the chromium half-cell to
the silver half-cell
d. the chromium electrode decreases in mass as the cell operates
