Question

reagent used to distinguish ozone and h2o2 is
​

Answer 1

Answer:

Colorimetry first with indigo trisulfonate for the ozone, then colorimetry using titaniumoxalate for the hydrogen peroxide and finally add iodide and titrate with thiosulphate to find the persulphate concentration.

Answer 2

Answer:

Potassium permanganate reagent is used to distinguish Ozone and H₂O₂.

Explanation:

• KMnO₄ is a powerful oxidizing agent and hydrogen peroxide itself a oxidizing agent. But when H₂O₂ reacts with KMnO₄ gives a redox reaction.  H₂O₂ acts as reducing agent and loss its electrons. The reaction of KMnO₄ and H₂O₂ is maintained by sulphuric acid. Oxygen gas is formed as product, the oxidation state of Mn is reduced from +7 to +2. Balanced chemical equation is given as:

        5H₂O₂ + 2KMnO₄ + 3H₂SO₄ $\longrightarrow$  2MnSO₄  + 5O₂  + K₂SO₄  + 8H₂O

• The ozone gas does not react with potassium permanganate.

         KMnO₄   + O₃ $\longrightarrow$  no reaction.

Therefore, KMnO₄ can be used to  distinguish Ozone (O₃) and H₂O₂.
