RE: rarely

A similar effect to burning a match is a result of the much stronger oxidizing power of KMnO4 than molecular oxygen (4 O atoms vs. 2 O atoms). A substance having a high number of C-H bonds is when added to it, fire chemistry happens.
KMnO4 + Glycrine (High concentration of C-H bonds) → Fire + Ash + CO2 + H2O

Sort:  

humm, it would be difficult to compare in this way to me. As the oxidizing power of KMnO4 is originated from the Mn(VII) high oxidation state. Higher number of oxygen atoms does not necessarily contribute to a stronger oxidizing power.
ie: CO2 have 2 oxygen atoms but is is not strongly oxidizing, when you compare with H2O2 which you also have 2 oxygen in it.
The oxidizing power are usually described in a thermodynamic point of view, where standard reduction potential would be the standard way of doing comparison.

Yeah @mcw it was this kind of mixture :-)

And thx for your response on the oxidizing power :-) ... saved me some typing. :-P

Haha ~
You used to play chemicals as well XDDD
