Eocell=Ecathode-Eanode Ecathode(Sn2+/Sn)=-0.14 Eanode(Zn2+/Zn)=-0.74 Eocell=-0.14-(-0.74) =0.74-0.14 =0.6 textV

Q. Standard reduction potentials of $S n^{2 +} / S n$ and $Z n^{2 +} / Z n$ electrodes are 0.14 V and $- 0.74 V$ respectively. What is the $E^{o}$ of the following cell in volts $Zn/Z n^{2 +} ∣∣ S n^{2 +} / S n$ ?

$- 0.6$

$- 0.88$

0.88

0.6

$E^{o}_{ce ll} = E_{c a t h o d e} - E_{an o d e}$ $E_{c a t h o d e (S n^{2 +} / S n)} = - 0.14$ $E_{an o d e (Z n^{2 +} / Z n)} = - 0.74$ $E^{o}_{ce ll} = - 0.14 - (- 0.74)$ $= 0.74 - 0.14$ $= 0.6 V$

Q. Standard reduction potentials of Sn2+/Sn and Zn2+/Zn electrodes are 0.14 V and −0.74 V respectively. What is the Eo of the following cell in volts Zn/Zn2+∣∣Sn2+/Sn ?

−0.6

−0.88

0.88

0.6

Eocell​=Ecathode​−Eanode​ Ecathode(Sn2+/Sn)​=−0.14 Eanode(Zn2+/Zn)​=−0.74 Eocell​=−0.14−(−0.74) =0.74−0.14 =0.6V

Q. Standard reduction potentials of $S n^{2 +} / S n$ and $Z n^{2 +} / Z n$ electrodes are 0.14 V and $- 0.74 V$ respectively. What is the $E^{o}$ of the following cell in volts $Zn/Z n^{2 +} ∣∣ S n^{2 +} / S n$ ?

$- 0.6$

$- 0.88$

$E^{o}_{ce ll} = E_{c a t h o d e} - E_{an o d e}$ $E_{c a t h o d e (S n^{2 +} / S n)} = - 0.14$ $E_{an o d e (Z n^{2 +} / Z n)} = - 0.74$ $E^{o}_{ce ll} = - 0.14 - (- 0.74)$ $= 0.74 - 0.14$ $= 0.6 V$
