Question
An iron wire is immersed in a solution containing ZnSO₄ and NiSO₄. The concentration of each salt is 1 M. Predict, giving reasons, which of the following reactions is likely to proceed:

(i) Iron reduces Zn²⁺ ions  
(ii) Iron reduces Ni²⁺ ions

Given:  
\( E^\circ_{(Zn^{2+}/Zn)} = -0.76 \, \text{V} \)  
\( E^\circ_{(Fe^{2+}/Fe)} = -0.44 \, \text{V} \)  
\( E^\circ_{(Ni^{2+}/Ni)} = -0.25 \, \text{V} \)
