Potassium permanganate `(KMnO_4)` is a strong oxidizing agent. Write any two oxidizing reactions of `KMnO_4`.

Potassium permanganate KMnO_(4) is not a primary standard Why?

Why are halogens strong oxidizing agents?

How do you account for the following observations? a) Though alkaline potassium permanganate and acidic potassium permanganate both are used as oxidants, yet in the manufacture of benzoic acid from toluene we use alcoholic potassium permanganate as an oxidant. Why? Write a balanced redox equation for the reaction. b) When concentrated- sulphuric acid is added to an inorganic mixture containing chloride, we get colourless pungent smelling gas 'HCl', but if the mixture contains bromide, then we get red vapours of bromine. Why?

Potassium permanganate and potassium dichromate are two transition metal compounds. Write any two uses of potassium permanganate.

Potassium permanganate acts as an oxidant in neutral, alkaline as well as acidic medium. The final products obtained from it in the three conditions are, respectively
