- A$Fe$
- B$Zn$
- C$Mg$
- ✓$Ag$
✓
Answer
Correct option: D.
$Ag$
d
(d) Because $Ag$ comes below in the electromotive series also standard electrode potential of $Cu$ and $Ag$ are:
(d) Because $Ag$ comes below in the electromotive series also standard electrode potential of $Cu$ and $Ag$ are:
$C{u^{2 + }}(aq) + 2{e^ - }{\mkern 1mu} \to Cu(s)$ ; ${\mkern 1mu} [SEP - E_{298}^o{\mkern 1mu} ({\text{volt}}) = \, + {\text{0}}.{\text{18}}]$
$A{g^ + }(aq) + {e^ - }\, \to Ag(s)$ ; $[SEP - E_{298}^o\,{\text{(volt) }} = {\text{ }} + {\text{0}}{\text{.80]}}$
