Standard emf ...

Question

Standard emf of cell = 0.463 vCu/ ${C u}^{+ 2}$ (M) ll ${A g}_{+}$ $(1 M)$ $1 A g$
If standard potential of Cu electrode is 0.337v then what is standard potential of Ag electrode?

Open in App

Solution

$E_{c e l l}^{0}$ = $(E_{C u / {C u}^{2 +}}^{0} + E_{{A g}^{+} / A g}^{0})$
$0.463 =$ $(- 0.337 + E_{{A g}^{+} / A g}^{0})$ $(∵ E_{{C u}^{2 +} / C u}^{0} = 0.337 V)$
$∴ E_{{A g}^{+} / A g}^{0} = 0.804 V$
