An electrochemical cell is set up with a Cu(s)|Cu(NO3)2(aq) electrode (Eored = +0.34 V) as well as an Ag(s)|Ag(NO3)(aq) electrode (Eored = +0.80 V). Choose the FALSE statement(s) concerning the operation of this celli) The concentration [Ag+] reduces at the Ag electrode.
ii) Electrons flow in the external circuit as of the Ag to the Cu electrode.
iii) Cu metal is a stronger reducing agent than Ag metal.
iv) The Cu electrode is the anode of the electrochemical cell.
v) Nitrate ions migrate as of the Ag half-cell to the Cu half-cell through the salt bridge.
