Question

The correct order of reduction potentials of the following pairs is
A. $Cl _{2} / Cl ^{-}$
B. $I _{2} / I ^{-}$
C. $Ag ^{+} / Ag$
D. $Na ^{+} / Na$
E. $Li ^{+} / Li$
Choose the correct answer from the options given below.

• A. A > C > B > D > E
• B. A > B > C > D > E
• C. A > C > B > E > D
• D. A > B > C > E > D

Answer 1

Answer: (A)

$E _{ Cl _{2} / Cl ^{-}}^{\circ}=+1.36 \,V$
$E _{ I _{2} / I ^{-}}^{\circ}=+0.54 \,V$
$E _{ Ag ^{+} / Ag }^{\circ}=+0.80\, V$
$E _{ Na ^{+} / Na }^{\circ}=-2.71 \,V$
$E _{ Li ^{+} / Li ^{\circ}}^{\circ}=-3.05\, V$
