Question

Write the redox reactions using half equations.

2Na(s) + Cl₂(g) → 2NaCl(s)

In the reactions given above, mention 

(i) Which reactant is oxidized? To what ?

(ii) Which reactant is the oxidizer?

(iii) Which reactant is reduced? To what?

(iv) Which reactant is the reducer?

Answer 1

3Na → 2Na⁺ +2e^– (oxidation)

Cl₂ + 2e^– > 2Cl^– (reduction) 

Na is oxidized to Na⁺ 

Cl₂ is reduced to Cl^–

Na is the reducer 

Cl₂ is the oxidizer.
