Problem
The same Zn–Cu apparatus is connected to an external power source so that copper metal is oxidized and zinc ions are reduced (that is, the Cu electrode functions as the anode and the Zn electrode functions as the cathode). Under these electrolytic conditions, which ion now migrates through the salt bridge toward the copper electrode?
(a) K+
(b) NO3−
(c) Zn2+
(d) Cu2+
