Question

Ozone act as oxidizing and reducing agent explain with example

Answer 1

Answer:

Ozone has all the electron affinity of O2 plus it is an endothermic compound. This makes it more reactive than O2. ... O3 usually reacts to oxidize with O2 being formed but sometimes all 3 O atoms are reduced.For example, with H2O2 and BaO2, it gives H2O and BaO respectively.

Answer 2

$PbS + 4O_3$ → $PbSO_4 + 4O_2$ [Oxidation]

$H_2O_2 + O_3$  ​→ $H_2O + 2O_2$ [Reduction]

Explanation:

Ozone act as oxidizing as well as reducing agent

• Ozone act as an oxidizing agent and a reducing agent

• Ozone decomposes to liberate nascent oxygen atoms.

Examples -

Oxidation reactions :

• Ozone oxidizes lead sulfide forming lead sulfate.

      $PbS + 4O_3$ → $PbSO_4 + 4O_2$

• Ozone oxidizes potassium iodide forming iodine.

      $2KI + H_2O + O_3$  ​ → $2KOH + I_2 + O_2$

• Ozone oxidizes Sodium hydrogen sulfite to Sodium hydrogen sulfate.

      $NaHSO_3 + O_3$ → $NaHSO_4 + O_2$

Reduction reactions :

• Ozone reduces hydrogen peroxide forming water.

    $H_2O_2 + O_3$  ​→ $H_2O + 2O_2$

• Ozone reduces barium peroxide forming barium oxide.

    $BaO_2 + O_3$ →$BaO + 2O_2$

• Ozone reduces ammonium hydroxide forming nitrogen and water.

   $2NH_4OH + 3O_3$  ​ → $N2 + 5H_2O + 3O_2$
