Question

Potassium (Atomic No. 19) and chlorine (Atomic No. 17) react to form a compound. On the basis of electronic concept, explain

(i) oxidation

(ii) reduction

(iii)oxidising agent

(iv)reducing agent

Answer 1

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^-
