उत्तर
2K + Cl2→ 2KCl
1.Oxidation: In the electronic concept, oxidation is a process in which an atom or ion loses electron(s).
K → K+ + e-
2.Reduction: In the electronic concept, the reduction is a process in which an atom or ion accepts electron(s).
Cl2 + 2e-→ 2Cl-
iii. Oxidising agent
An oxidising agent oxidises other substances either by accepting electrons or by providing oxygen or an electronegative ion, or by removing hydrogen or an electropositive ion.
Cl2 + 2e-→ 2Cl-
iv.Reducing agent
A reducing agent reduces other substances either by providing electrons or by providing hydrogen or an electropositive ion, or by removing oxygen or an electronegative ion.
K → K+ + e-
