MCQ
In the cell $Zn\,\,|\,\,Z{n^{2 + }}\,\,||\,\,C{u^{2 + }}\,\,|\,\,Cu,$ the negative electrode is
- A$Cu$
- B$C{u^{2 + }}$
- ✓$Zn$
- D$Z{n^{2 + }}$
✓
Answer
Correct option: C.
$Zn$
c
(c)In the cell $Zn|Z{n^{2 + }}||C{u^{2 + }}|Cu$the negative electrode (anode) is $Zn.$ In electrochemical cell representation anode is always written on left side while cathode on right side.
