A galvanic cell consists of one half-cell that contains Ag(s)and Ag⁺(aq),and one half-cell that contains Pb(s)and Pb²⁺(aq).What species are produced at the electrodes under standard conditions? Ag⁺(aq)+ e^- → Ag(s)E° = +0.80 V Pb²⁺(aq)+ 2 e^- → Pb(s)E° = -0.13 V A)Ag(aq)is formed at the cathode and,Pb(s)is formed at the anode. B)Ag(s)is formed at the cathode,and Pb²⁺(aq)is formed at the anode. C)Pb(s)is formed at the cathode,and Ag⁺(aq)is formed at the anode. D)Pb²⁺(aq)is formed at the cathode,and Cu(s)is formed at the anode.

The cathode is where reduction occurs, and the anode is where oxidation occurs. Given the standard electrode potentials, Ag+ is reduced to Ag(s) at the cathode because it has a more positive E° value (+0.80 V), indicating it is more likely to gain electrons. Pb is oxidized to Pb^2+ at the anode because its reaction is written in the reverse direction for oxidation to occur, and it has a less positive E° value (-0.13 V), indicating it is more likely to lose electrons.
