1.	Give one example showing reducing property of ozone.
Answer» Ozone decomposes to liberate nascent oxygen, hence it is a powerful oxidising agent. O_3(g) → O_2(g) + O For example : (i) It oxidises lead sulphide (PbS) to lead sulphate (PbSO₄). pbS_(s) + 4O_3(g) → pbSO_(s) + 4O_2(g) (ii) Potassium iodide, KI is oxidised to iodine, l₂ in the solution. 2Kl_(aq) + H₂O₍₁₎ + O_3(g) → 2KOH_(aq) + I_2(s) + O_2(g)

Answer»

Ozone decomposes to liberate nascent oxygen, hence it is a powerful oxidising agent.

O_3(g) → O_2(g) + O

For example :

(i) It oxidises lead sulphide (PbS) to lead sulphate (PbSO₄).

pbS_(s) + 4O_3(g) → pbSO_(s) + 4O_2(g)

(ii) Potassium iodide, KI is oxidised to iodine, l₂ in the solution.

2Kl_(aq) + H₂O₍₁₎ + O_3(g) → 2KOH_(aq) + I_2(s) + O_2(g)
