The overall reaction is Cl2 + 2Ag --> 2Ag+ + 2Cl-
The Ag+ travels through the porous barrier to the anode
The Cl- travels through the porous barrier to the cathode.
In the anode, there are Ag+, Na+ (is there Cl- too? ... because if there is AgCl is a precipitate)
In the cathode, there are Cl-, NO3- (is there Ag+ too? (how far to completion has the reaction gone? ... because if there is AgCl is a precipitate)
