Question

Write the redox reactions using half equations.

Zn(s) + PbCl₂(aq) → Pb(s) + ZnCl₂(aq)

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

Zn → Zn²⁺ + 2e^– (oxidation), 

Pb²⁺ → 2e^– +Pb (reduction) 

Zn is oxidized to Zn²⁺ 

Pb²⁺ is reduced to Pb 

Pb²⁺ is the oxidizer

Zn is the reducer.
