When concentrated sulfuric acid is added to solid potassium permanganate, Mn2O7 (Manganese heptoxide) is formed.
Mn2O7 is a green volatile oil, wich is an extremely strong oxidiser and almost any organic material will ignite on contact. Here this is demonstrated with a glass rod, wetted with ethanol.

WARNING: manganese heptoxide is very hazardous and should only be prepared in very small qunatities.

  • Well, the main reason is because it is the anhydride of permanganic acid. Meaning that the manganese atoms are in their highest oxidation state, and there is a weak Mn-O-Mn bond between two fully oxidized Mn atoms...Hmm I suppose that was a bit redundant, wasn't it?

    I gotta type fast here, cause I gotta get off here, but it does have to do with the anhydride linkage...why not just google it?Not tryin to be a dick, I'd gladly explain, but I really have to get off here now. Hope that helped!

  • Can someone explain why manganese heptaoxide is such a strong oxidizer? I mean most oxiders, even perchlorates/chlorates and permanganates don't react that violently and easy witch reducing agents.

  • Sorry, accidentally pressed on the button. I actually prepared some Manganese heptoxide in a test tube once, it was pretty strong.

  • I actually prepared some Mangan
