Question
What do you understand by redox reactions? Explain oxidation and reduction in terms of loss or gain of electrons.

Solution
Transfer of electron(s) is involved in the formation of an electrovalent bond. The electropositive atom undergoes oxidation, while the electronegative atom undergoes reduction. This is known as a redox process.
Oxidation: In the electronic concept, oxidation is a process in which an atom or ion loses electron(s).
Zn → Zn2+ + 2e-
Reduction: In the electronic concept, the reduction is a process in which an atom or ion accepts electron(s).
Cu2+ + 2e-→ Cu
