An electrochemical cell is constructed in which one half-cell contains AgN03 solution in contact with an Ag strip, and the other half-cell contains magnesium nitrate solution, Mg(N03h, in contact with a Mg strip. The two solutions are connected by a salt bridge, and the two metals are connected by a copper wire.
(I) Which ion, Mg2+ or Ag+, is more easily reduced in aqueous solution?
