When potassium permanganate is titrated against ferrous ammonium sulphate in acidic medium, the equivalent mass potassium permanganate is ,

When an acidified solution of ferrous ammonium sulphate is treated with potassium permanganate solution, the ion which is oxidized is

Write the formula of the following salts : Potassium permanganate

Give preparation of Potassium Permanganate (KMnO_4) .

What is the oxidation number of Mn in Potassium Permanganate ?

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:

Why does a large volume of water get coloured due to a few crystals of potassium permanganate ?
