Question

What will be the emf of the following concentration cell at 25°C? Ag(s)|AgNO3(0.01 M)||AgNO3(0.05 M)|Ag(s) (A) 0.828 V (B) 0.0413 V (C) -0.0413 V (D) -0.828 V

Tardigrade Admin · Accepted Answer

E=E°-(0.0591/n)log Q E°=0 for all concentration cells =0-(0.0591/1) log ((0.01/0.05)) =0.0413 V

Q. What will be the emf of the following concentration cell at $2 5^{\circ} C$ ?
$A g_{(s)} ∣ A g N O_{3} (0.01 M) ∣ ∣ A g N O_{3} (0.05 M) ∣ A g_{(s)}$

$0.828 V$

$0.0413 V$

$- 0.0413 V$

$- 0.828 V$

$E = E^{\circ} - \frac{0.0591}{n} l o g Q$
$E^{\circ} = 0$ for all concentration cells
$= 0 - \frac{0.0591}{1} l o g (\frac{0.01}{0.05})$
$= 0.0413 V$
