Question

$E^{o}$ for $F e^{2+}+2 e^{-} \rightarrow F e$ is $-0.44$ volt and $E^{o}$ for $Z n^{2+}+2 e^{-} \rightarrow Z n$ is $-0.76$ volt thus:

• A. $Zn$ is more electropositive than $Fe$
• B. $Zn$ is more electronegative than $Fe$
• C. $Fe$ is more electropositive than $Zn$
• D. none

Answer 1

Answer: (A)

$Zn$ is more electropositive than $Fe$

Answer 2

High value for $E_{\text {red }}^{o}$. shows more electro negativity i.e., $Z n$ is more electropositive than $Fe$. $\left(E^{o}_{Z n^{2+} / Z n}< E_{F e^{2+} / F e}^{o}\right)$
