Question
Which of the following represents the anode half-cell reaction for the following galvanic cell: Cu(s)|Cu2+(aq)||Ag+(aq)|Ag(s)
Answer: Option B
:
B
Reduction reaction takes place at cathode and oxidation reaction takes place at anode.
Cathode :2Ag+(aq)+2e−→2Ag(s)
Anode :Cu(s)→Cu2+(aq)+2e−
Cell reaction :Cu(s)+2Ag+(aq)→Cu2+(aq)+2Ag(s)
