Question: (I) $ H _2O _2,+O _3,\xrightarrow{,},H _2O,+2O _2 $ [AIPMT 2014]

(II) $ H _2O _2+Ag _2O\to 2Ag+H _2O+O _2 $ Role of hydrogen peroxide in the above reactions is respectively

Options:

A) oxidising in (I) and reducing in (II)

B) reducing in (I) and oxidizing in (II)

C) reducing in (I) and (II)

D) oxidising in (I) and (II)

Show Answer

Answer:

Correct Answer: A

Solution:

  • In the reaction, Since $ H _2O _2 $ oxidises, $ O _3 $ into $ O _2 $ , thus it behaves as an oxidising agent. Further, in the reaction, Here $ H _2O _2 $ reduces $ Ag _2O $ into metallic silver [Ag] (as oxidation number is reducing from +1 to 0). Thus, $ H _2O _2 $ behaves as a reducing agent.
