Question

Consider the follwoing reduction processes :
$Z n^{2 +} + 2 e^{-} \to Z n (s); E^{0} = - 0.76 V$
$C a^{2 +} + 2 e^{-} \to C a (s); E^{0} = - 2.87 V$
$M g^{2 +} + 2 e^{-} \to M g (s); E^{0} = - 2.36 V$
$N i^{2 +} + 2 e^{-} \to N i (s); E^{0} = - 0.25 V$

The reducing power of the metals increases in the order :

N i < Z n < M g < C a
