Redox Reactions And Electrochemistry Ques 709

Question: Given the following half reactions:

$A^{2 +} + e^{-} \to A^{+}, E^{o} = + 1.70 V$ $B^{2 +} + 2 e^{-} \to B^{+}, E^{o} = + 0.60 V$ $C^{3 +} + e^{-} \to C^{2 +}, E^{o} = + 0.90 V$ The only reaction that could be used in titration would be

Options:

A) $A^{+}$ with $B^{4 +}$

B) $A^{+}$ with $C^{3 +}$

C) $A^{2 +}$ with $C^{2 +}$

D) $C^{2 +}$ with $B^{4 +}$

Show Answer

Answer:

Correct Answer: C

Solution:

[c] $\begin{aligned} , A^{2} + e^{-} \to A^{+}, E = 1.7 V \\ C^{2 +} \to C^{3 +} + e^{-}, E^{\circ} = - 0.9 V \\ A^{2 +} + C^{2 +} \to A^{+} + C^{3 +}, E^{\circ} = 0.8 V > 0, \end{aligned}$ spontaneous.
