Question

CuSo4 + Fe = Cu + FeSo4- write oxidation and reduction equations from the above reaction

Answer 1

First of all, let us talk about a broader meaning of oxidation & reduction, rather than just in terms of oxygen and hydrogen.

Oxidation:

• Loss of electrons
• Gain of electronegative element
• Loss of electropositive element

Reduction:

• Gain of electrons
• Gain of electropositive element
• Loss of electronegative element

Now,the charge on all these ion are as;

Cu⁺²SO₄⁻² + Fe⁺² = Cu⁺² + Fe⁺²SO₄⁻²

• Cu is electropositive
• SO₄ is electronegative
• Fe is electropositive

As,

• Cu is losing a electronegative element so, CuSO₄ is getting reduced
• Fe is gaining a electronegative element, thus Fe is getting oxidized.

Conclusion: Oxidation - Fe & Reduction - CuSO₄

[Equation of both oxidation & reduction is already there,amn't getting the question properly.]
