Question

$- E_{oxid}$ values of $\rightarrow$ is $\rightarrow$, of $\rightarrow$ is $\rightarrow$ and $\rightarrow$ is $\rightarrow$. Which of the following statements is correct .

• A. $\rightarrow$ will reduce $\rightarrow$
• B. $\rightarrow$ will reduce $\rightarrow$
• C. $\rightarrow$ oxidises $\rightarrow$
• D. $\rightarrow$ oxidises $\rightarrow$

Answer 1

Answer: (A)

$\rightarrow$ will reduce $\rightarrow$

Answer 2

$E_{Zn^{+ +}/Zn}^{o} < E_{Fe^{+ +}/Fe}^{o}$, so Zn will reduce $Fe^{+ +}$. $Zn$ cannot reduce $Mg^{2 +}$ because $E_{Zn^{+ +}/Zn}^{o} > E_{Mg^{+ +}/Mg}^{o}$

On similar reason Mg and $Zn$cannot oxidize $Fe$.
