Electrochemistry - Result Question 45
####47. A hypothetical electrochemical cell is shown below
$A|A^{+}(xM)||B^{+}(yM)| B$
[2006]
The emfmeasured is $+0.20 V$. The cell reaction is
(a) $A^{+}+e^{-} \to A ; B^{+}+e^{-} \to B$
(b) The cell reaction cannot be predicted
(c) $A+B^{+} \to A^{+}+B$
(d) $A^{+}+B \to A+B^{+}$
Show Answer
Solution:
- (c) The cell reacton is as follows :
$A \to A^{+}+e^{-}$ $\frac{B^{+}+e \to B}{}$ ${arrow A^{+}+B} }$
