Exothermic reaction Potassium Permanganate

[nicktohzyu]

in my country, KMnO4 is legal but S8 is not -.-

[monkeysdman1]

"i wonder if its hot!"... "OUCH!"

[banjax66]

Would 'glycerine' be a shortened name for nitroglycerine by any chance?

[Watevanow]

@banjax66 no it is not, glycerine is a product in its own rights

[MrLuka58]

very cool what is the ingrediance

[12345abcqwerty]

WTF??

[Izoto593]

Wow, I would be embarrassed if I was camping and a chemistry buff burst out this and made a fire in seconds with 0 effort.

[JetJockey87]

So I guess its the Glycerol that reacts to the Potassium Permanganate? As only the glycerol burnt up, if it were the other way around all the condys crystals would burn up right?

[beybladera]

@JetJockey87 No, its a reaction between the two substances. If you have a cup full of glycerin and you put the potassium permanganate in, only the places where the crystals meet the glycerin would burn up, and it would happen a lot faster because it is a solid going into a liquid, so more surface area.

[Karvenate]

First of all, it wasn't really big because the dusty crystals aren't too big!

[22matt19]

damn the one time i find a chemical supplier to canada they dont sell kmno4 also why waste it to do this simple reaction

[360Degrez]

yeah flippin terrorist make it hard for we chemistry nerds to have fun...

[riveraluciano]

ohhh i remember doing this reaction with crocodile physics :D

[MacsCanfly]

an error accrued, pleas try again later.

[Brianshvrs]

How stable is potassium permanganate? This looks like it may be useful for camping, but I don't want to get anyone hurt.

[ananddev]

Yes, it can definitely be used for camping. It has been used in military survival kits to purify water (very dilute solution), as an antiseptic (slightly concentrated solution), marker in snow in addition to its ability to start fire with glycerine.

[Brianshvrs]

Good. Thank-you.

[vaper192]

@Brianshvrs it i a oxidizer

[dragonridley]

I take the Potassium permanganate acts as an oxidizer?

[metalheadrowi]

Indeed, Potassium permanganate is a very strong oxidizing agent!

[elliotmotocross]

I got that shit on my hands and it burned soooo bad

[chemy999]

in this experiment are glycerol and glycerine interchangeable

[Tdnmen2]

OMG volcano :P

[pyropakman]

Where do you get potassium permanganate? I'm pretty sure you can get glycerin at a pharmacy no doubt.

[ananddev]

Do a google product / Shopping search for potassium permanganate. You will find a lot of online stores selling it.

[elliotmotocross]

chemist...

[SecretKillerr]

go to pharmacy and ask for it.. it's used to clean wounds ( like 3g for 100ml of water)

[RoflMoar]

Just DO NOT buy them at the same store or even on the same day... hahah. terrorists suck!!!

[antiswattt]

or never go ask for any metal fuel (aluminium powder, magnesium.. magnalium) :D if they know about chemistry youre fucked haha most people thinks im a terrorist because i tried to buy kmno4 (i ahd to be 18 DOH) and then also calcium carbide lol i said calcium carbide make acetylene gas haha and then they wouldnt let me buy fucking bitches :D

[vaper192]

@pyropakman ebay

[sciencoking]

would ethanol work?

[TakronRust]

No, Glycerin.

[chemy999]

are glycerol and glycerin interchangable?

[TakronRust]

Yes, they are the same thing sir.

[starfire110]

gun powder?

[BuffaloWarrior7]

potassium Permangante...not gun powder

[Smartgrl123]

wow lol...that was short :)

[NinjaKid3000]

where do you get those things from??

[HackthenSkate2]

look around your house and youll find both.

[sublime6636]

at wallgreens cvs ect..

[NinjaKid3000]

lol u lucky americans with your supermarkets that have everything

its okay in canada but u guys have the works

[sublime6636]

i want to move 2 canada how is it?

[NinjaKid3000]

really? if u live in america i suggest staying there. its better than canada. but if john mccain becomes president then what the heck move here

[sublime6636]

no kidding.

[NinjaKid3000]

im not saying canada sucks its just that america seems so much more exciting

[omgcandy]

Canada is wonderful! :D Gah, and right now the Canadian dollar isn't doing so well, so if you come down here, you'd be able to buy loads of stuff for cheap. >>;

[gonjiam]

does anyone no a site i can buy this stuff in crystal form online?

[rastagyerek]

The glass were buy in the IKEA, isn't it?

[noxnox11]

ooo shiny......cool experiment.......

[VideyoJunkei]

I love the long delay.... wait for it, wait for it!

[Wildmonky3000]

THAT WAS ON SURVIVERMAN

[sublime6636]

lol

[bagladyssuck]

Do you mean Survivorman?

[lickthebubble]

you get the lyquid from snakebite kit

[michaelharper110]

i did this at school but on a much larger scale and that thing blew up in my face and i nearly shit myself.

[Maxshaki]

super i loved videos!!!

[pyromancer91]

how much is the powdered alluminum and magnesium strips??? plx

[HarrisonMilburn]

powder aluminium is expensive and hard to get. Try ebay

[maleksimon]

I still did not watch the video yet, but talking about aluminum powder for not finding it, why not try using Zinc powder instead. Remember potassium permanganate is an oxidizer,and for that you do not mix zinc or aluminum with.

[pyromancer91]

I was talking about thermite...

for this you need aluminum because of its properties such fusion and boinling points, you need it to make the reaction go over 2000 celcius degress.

other metal can be used but the aluminum will give a better reaction

[ananddev]

this is not powdered alluminum and/or magnesium. It is powdered potassium permanganate.

[pyromancer91]

yes I know but...

thermite rocks xD

[XSTEALTHSHADOWX]

could this be the new revolution in car fuel..im no science freak..but it does seem to put up quite a flare..is the oxidizer a rare substance?

[mserebreny]

not rare, it's glycerin

[emby721]

the oxidiser is the kmno4 dickwad

[mserebreny]

You're absolutely right. But since kmno4 is Potassium Permanganate and is listed in the tile of the video, I assumed the one who asked the question did not know that (as denoted by the "I'm no science freak") was mistakenly referring to the liquid that was poured in, as it was not mentioned before.

.... and I won't stoop to your level and call you something even worse in return :)

[Strongbad662000]

kmno4 is the oxidiser dickwad

[mserebreny]

we've established this already... having a slow day? well better late than never I suppose

[michaelharper110]

SNAP! lol

[AirsoftLife]

you certainly don't want to overfuel your oxidizer do you? lol. nice demo

[alphamone]

this is a way to set off a thermite reaction, though magnesium fuses tend to be far less touchy as you just light it and stand the hell back, instead off adding these two chemicals and waiting.

/tangent.

[johnnywhatsup]

The British SAS has this in their Survival Guide. Could never find out from where they had gotten the Potassium. Someone had told me a certain kind of foot powder/ anti fungal something or other. I have looked for it in Pharmacies but have not found it. Wanted to add it to my first aid/survival kit. Anyone know where to find a common source?

[ananddev]

the "Penrith Survival tin" contains potassium permanganate. Google for "Penrith Survival tin"

[AirsoftLife]

ask your water guy. I got mine for free. xD

[flipsuperstar]

I got mine from boots. Every soldier got to have this stuff, does about 4 diff things and takes up no space. = )

[frogman5452]

It is used as a water treatment for people using wells as an example. It's about $24 for a quart or so. The stuff will stain just about anything a really intense purple color. Anti freeze and brake fluid can be used to mix. There may be a cheaper source but I can just drive a couple of miles and come home with all I would ever want.

[18thcp]

The stain should become brown, as permangante decomposes into Mn2O3. this can be removed by mixing dilute acid (hydrochloric, citric and tartaric acid wrok well) with hydrogen peroxide. the h2o2 is oxidised producing o2 that frees the particles and the acid dissolves the Mn, removing the stain. wash out the acid though or you may develope a hole :>

[18thcp]

Soz mistake "(hydrochloric, citric and tartaric)" should be (hydrochloric, citric /or/ tartaric) sorry

[jmmatos23]

Have you ever tasted glycerine? it is sweet. For that reason it is used in some medicines, to disipate strong tastes, but thats not the point. I dont get how and why does a compound like glycerine would react that way with potassium permanganate. Can you explain? Thanks.

[blargd]

the Potassium Permanganate is a very strong oxidising agent and oxidises the Glycerol which is very suspectable to being oxidised so when you put them together voila this happens, I know this cos our Chem lecturer tried this other day ended up getting a bit too enthusiastic and burning a hole through the tin lid he did it on

[blargd]

and basically welding it to the fume cupboard before realising the fan wasnt working so we had to get out of the room as it was smokeing up quite a bit lol

[mi4mercenary]

wth liquid make flare????

[ananddev]

Hmmm don't know an interesting thing to consider. May be some one out there could answer this better.

[Forlo12345]

To answer your question: potassium permanganate is a powerful oxidizing agent. Glycerine has an affinity to be oxidized. When the two chemicals come into contact, they form a spontaneous, exothermic, redox reaction, in that it gives off tremendous amounts of heat energy. The flame you saw was just the rapid release of energy that was so intense that it burned the surrounding oxygen.

[mi4mercenary]

im no science guy. or i AM but i havent learned about chemistry yet, im only in eighth grade. but that very cool

[chester73]

classic redox reaction. nice

[UltimateFlameX]

okay. cool thx ^_^ btw, thx for uploading this video.

[UltimateFlameX]

I c. So can u tell me why this is an exothermic reaction? Thx

[ananddev]

I guess that is because the total energy required to break the bonds is less than the energy released during the making of the molecular bonds. Resulting in a net gain. That is the heat required to start the reaction is less than the heat generated by this reaction. This extra energy results in the heat and light produced.

Hey but I am not a chemistry major so this is the best I can do for an explanation. :-)

[Forlo12345]

you're on the right track. actually, that much is true for the general understanding of heat transfers, but in this case, what causes the exothermic process to occur is the rapid, spontaneous transfer of electrons from the glycerine to the permanganate anion. This reduces the oxidation number of the manganese atom because it gains more electrons, and releases a lot of heat energy in the process.

[UltimateFlameX]

In other words, is it an exothermic reaction because the glycine transferred its heat to the Potassium Manganate?

[ananddev]

No. Heat it the byproduct of the reaction. Just like CO2 and water (H2O) are also produced. Heat is also a result of this reaction. Stating it in another way

14 KMnO4 + 4 C3H5(OH)3 --> 7 K2CO3 + 7 Mn2O3 + 5 CO2 + 16 H2O + Heat

[UltimateFlameX]

How do we know what to consider the system?

[ananddev]

I didn't understand your question. What to consider in what system?
