Electrochemistry - Result Question 36

####38. Standard electrode potential for $S n^{4 +} / S n^{2 +}$ couple is $+ 0.15 V$ and that for the $C r^{3 +} / C r$ couple is $- 0.74 V$ . These two couples in their standard state are connected to make a cell. The cell potential will be :

[2011]

(a) $+ 1.19 V$

(b) $+ 0.89 V$

(d) $+ 1.83 V$

Show Answer

Solution:

(b) The couple for which SRP value is high, will act as cathode and the other couple will act as an anode.

$\begin{aligned} E_{cell}^{0} & = E_{cathode}^{0} - E_{anode}^{0} \\ = 0.15 V - (- 0.74 V) = + 0.89 V \end{aligned}$
