Homework Statement
Pb/Pb2+ and Ag/Ag+
Ni/Ni2+ and Zn/Zn2+
Which one is the anode and cathode?
Toward which metal do the electrons flow?
The Attempt at a Solution
2Ag2+ + Pb ⇔ 2Ag + Pb2+
Pb is anode
and Ag is cathode
e- go toward Ag.
Zn + Ni2+ ⇔ Zn2+ + Ni
Zn is anode
and Ni is cathode
e- go toward Ni.
Is this correct?
Thanks.
