I somehow see why there are restrictions and some kind of regulations for buying KMnO4. It does have quite some oxidizing power. Unfortunatelly I can not find the video right now where a friend of mine and I experimented with some leftovers of this substance and got really nice results: A jet of a flame and a molten can of aluminium. - :)
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
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.

Haha i guess permanganate with glycerol? (The first part of the video)

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
@mcw, 棒棒哒！
有聲的 XD (有點臺灣人說出來的感覺 XD)
在水中溶化以后就是紫色的了。我小时候，我妈曾经用这个东西来洗脚，她说这个东西消毒。
我当时很喜欢这个紫色的液体，很漂亮的透明的紫色。至于是不是能消毒，我就不得而知了。
哈哈對啊對啊，真的是能消毒的。（超強的氧化劑，什麽細菌都會被氧化殺死）
遠足的人好像還會用作後備淨水劑！
原来我妈不是乱盖的哈哈。她当时好像是从国有企业的医务所开药开的，好像不是免费就是很便宜，不可能有85美元这么贵，不然这消毒液 真是太贵了哈哈哈哈哈
哈哈，老人家的智慧都是經驗累積而來的XD
消毒液含有的高錳酸鉀其實是只有很少的
(很少的量顏色已經很強了)
要不然把你的皮膚氧化掉就不好了XDD
所以洗完就變黃金腳 XDD
Haha
你說起黃金腳讓我突然想起香港腳🙊😂
那就~~ 讓香港腳洗一洗,殺菌後變黃金腳 XDD
不要沒結果啊xDDD 讀到最後還是沒結果讓讀者好糾結！
結論是好像買回來會簡單一點🤣🤣🤣
(總是有些騎呢途徑能買這些簡單的東西😂😂)
