Write ionic equation showing `KMnO_4` acting as an oxidising agent in acidic medium.

Why does O_3 act as a powerful oxidising agent ?

SO_2 acts as oxidising and reducing agent.

How does KMnO_4 act as a powerful oxidizing agent in neutral, alkaline or acidic medium ?

Write one oxidising reaction of KMnO_4 in basic medium.

Give one reaction to show that H_2O_2 is oxidising agent.

Which of the following acts as both reducing and oxidising agent ?

Stannous sulphate (SnSO_(4)) and potassium permanganate are used as oxidising agents in acidic medium for oxidation of ferrrous ammnium sulphate to ferric sulphate. The ration of number of moles of stannous sulphate required per mole of ferrous ammonium sulphate to the number of moles of KMnO_(4) required per mole of ferrous ammonium sulphate, is:

Give two reactions of each where hydrogen acts as an oxidising agent and reducing agent.
