In a galvanic cell composed of a Zn(s)∣Zn2+(aq) half-cell and a Cu(s)∣Cu2+(aq) half-cell, a salt bridge containing 1.0MKNO3 connects the two compartments. Electrons flow spontaneously from zinc to copper. Which ion migrates through the salt bridge toward the copper electrode?
(a) Cu2+
(b) K+
(c) NO3−
(d) Zn2+
