Chemistry experiment - KMnO4 + NaOH + sugar

[thariachanz]

wow nice trick!

[SilverCalculatorApp]

cool trick

[tibby499]

0:49 Some V8 passed by. ;)

[hairytoothgaming]

This makes a sweet magic trick! ;)

[rhesaashley9]

lv it n lv chemistry..

[Crocodileyay]

damn chemical you scary

[srm13560]

my daughter loves helping me out at this... ;DDD soon enough will show my nephew, such a fine magic trick to perform on a rainy day!!!

[TimothyParadox1]

Pretty cool =D

[MissBloodieMelMarrie]

HUGE LIKE ! cause it's chemistry !!!!!

[Fii12]

Very interesting experiment. Could you tell me the concentrations of KMnO4 + NaOH you used, please?

[AssassinOfTrolls]

@Fii12 I did this experiment, and I used maybe spoonful of NaOH(25% solution) and I dissolved few KMnO4 crystals in water. It was small scale though. Btw, I don't think concentrations really matter.

[bomb1234able]

sodium or sugar?0:37

[Jvk156]

@bomb1234able its sugar!!!

[tomekkk10000]

@bomb1234able NaOH - characteristic granules

[CPCWC]

how lobg does the effect last?



[tuananh605b]

the miracle of chemistry

[simplyincognito]

hope that went in a waste container and not the sink...

[commercialmats]

That is pretty cool. I think it is interesting how it will change between more then 2 colors like that.

[RsGhost1]

Wow :O I assume the NaOH is used to slow the dissolving proces of MnO4?

[duniastaa]

Ok, i did it myself on my chemistry lesson. It does work, but You need to get the right balance of those ingredients. We did it exactly like on this vid but we needed to put some water into K2MnO4 bcoz firstly it was too dark... Sorry for my english mistakes, i am from Poland ^ ^

[edukid1984]

@duniastaa

Your Enligsh is just fine. Much better than some self-proclaimed native speakers who can't even spell properly!

[duniastaa]

@edukid1984

Yay, thank You :))

[duniastaa]

1stly You added sugar, then NaOH and then KMnO4 ?? Is that right??

[DavidEdwardSchnell]

Yahoo!

[Taytay1413]

What is the formula for this reaction?

[JRV95]

@Taytay1413

KMnO4 (Potassium Permanganate) + NaOH ( Sodium Hydroxide) + C6H12O6 (Glucose) ->

Not sure about the products, so that means it probably isn't balanced but those are the reactants. I would work it out and put the states of the products and reactants but I'm lazy and I want some cheese sticks.

[Chmielok]

There is no orange, because Mn 3+ nearly doesn't exist. There are pale pink Mn 2+.

[Sigma1694]

sugar,spice and everything nice...

[laurenseman]

cool how u gotit 2 change colors like that. bravo.

[hematitecrow]

Skip to 1.15 to save 47 seconds of your life.

[cesarflanatico17]

Mn nox = +7 purple

Mn nox = +6 green

Mn nox = +4 brown

[janishani77667766]

how thiz

[Cloud9er]

dude you need labels on your video or some talking...

[xueyuki]

hello! may i know the proportions of your reagents? what was your concentration of NaOh and KMnO4 in the first place?^^ thank you!

[MrsBazzingaa]

can you tell me which is which?!?!

[TirianB]

@MrsBazzingaa I don't think they purple stuff is the sugar.

[yongrenjie]

@MrsBazzingaa Well the extremely cool purple liquid in the beaker is potassium permanganate. The solid is sugar, it can't be sodium hydroxide because NaOH is extremely hygroscopic. The other one is sodium hydroxide.

[FractAlkemist]

There's something better you can do with KMnO4. Shovel a little into a test tube, then add a couple ml H2SO4. Shake gently a few minutes till you see a dark pretty green liquid. Then drop a popsicle stick or wood twig into it. Be sure you are filming so you can post it here.

[pyropakman]

@FractAlkemist :Yeah....don't do that. You make the dangerous anhydride, Manganese Heptoxide, Mn2O7. Any organics in the vicinity will combust vigorously and dangerously.

Any dirt, any dust, any residue on the inside of a flask: it counts.

[agentdarkboote]

That was pretty awesome.

[pf1624ablereal]

NaOH as negative catalyst

Sugar as RA

MnO4- as OA

Thanks enormously for illustrating this coz I have to persuade my chemistry teacher to carry out such performance in science week ^_^

[Ahlwwy]

that why kmon4 is self indcatior

btw this process should done under titration method

[gunluvinnut]

Really worth watching!! not.

[superb150]

Thank you so much for this :D i will do this on my chemistry project ^_^

[oldtimestv]

Are u sure that green color cause of the Mn 3+ ?

[douro20]

He's using NaOH and sugar as a reagent...

[philoplatt]

so what does it taste like?

[LameSkaterTM]

axaxaxaxax

[MrYounoober]

wow cool!

[Ilovesunshine1992]

why ? Can anyone explain to me ?

[Agentoxedo07]

Holy-Terrorist:>*=* wow, really is sodium hydroxide and sugar(saccharose) and potassium permanganate for haves it !

[22matt19]

your getting really fucking annoying

[willemotten]

ok.. nice ;)

[darkanonymousd]

omfg he's turning in to shit !!! run save yourself !!!

[jjasperchan]

im sure permanganate and sugar are explosive...

not dissolved in water though

[wattapassa]

actually, permanganatr and sugar are explosive, and water is often what causes it to ignite.

[galeonnightwind]

Hot, acidified potassium permanganate is more reactive; in this case, cold, alkali was used instead, so the reaction is not vigorous.

[dominostandard]

I'm in grade 8. My science teacher put something potassium in water and it turned the water purple. Then he put these white crystals in. It turned the solution brown. When he added more of those white crystals, you could see the water change from dark brown, to brown, to light brown, then to clear!

[galeonnightwind]

The water was mixed with an indicator called phenolphthalein, which turns into purple when an alkali solution is present, potassium makes the water alkali, the white crystal should be some acidic crystals to shift it back to colorless, acidic solution.

[JaksProductions]

I have some KMnO4 in home for chemistry experiments... should I put a small oxidizer icon on it? =]

[habbopassload]

You should put a large oxidizer icon on it

[pyropakman]

Definitely.

[antiswattt]

damn.. totally havce seen those comments before O_O

[majorenosburaot13]

may i know the introduction of this experiment?

[profesorakif]

Danke schön dafür, thanks...

[lukepevensie]

so heat changes color in chemicals am i correct

[KamilHaur]

no, its the way chemicals refract light, and the magnesiumperoxide ions lose and gain electrons, so the "molecules" change. this causes different colors.

[mingmingnak]

its not quite refracting light and the molecules changing that causes the color change..it has to do with the molecular orbitals and unpaired orbitals...in the metal...if you may have noticed transition metals/ compounds have unpaired electrons and this is where the diffrent colors originate

[Peacefulrules2]

we learned nothing but color change

[talkinglens]

What happened? What did we learn. What were the reactions and end products? We don't know!

[tomabiochimistul]

Normal oxidarea ar trebui sa aiba loc in mediu acid ( H2SO4)unde permanganatul de K isi manifesta la maxim caract. oxidant ( schimba 5e-)

[GetMeThere1]

awesome!

[davecool67]

mix it with mo44

[MrGameAndWatch00000]

what can I use for the NaOH???

[AirsoftLife]

Uh...NaOH maybe?

[Mekill60]

Erm.. Lye is a common name.. err.. yeah.

[chao129]

look for drain cleaner that has a high content of sodium hydroxide

[xR0WDYx]

also called caustic soda. I found a drain cleaner that is 100% NaOH.

[MummyFish1012]

liar. they aren't allowed to go above 20%.

[xR0WDYx]

nope, i tested it myself

[MummyFish1012]

yes, well I walked on the moon while Jimi Hendrix played guitar with me.

Have proof?

[xR0WDYx]

when i say i found it. i mean, i came across it in the mechanical engineering building of my university where i work. it was a brand drain cleaner. i dont remember the brand but i stil have the granular form (not bead form, though i have that too) in a storage container. It reacts quickly with aluminum shavings, heats up like crazy when dissociated in water, and though its not reagent grade, i bet I could saturate a solution with it and get within 1-5 percent of reagent grade.

[xR0WDYx]

oh and it said on the bottle that it was 100 percent. Ill throw a little error in there since its not reagent quality.

-psh you didnt walk on the moon, silly!

[a1a2b3b4202]

SO COOL!!!!

[Siegheiler]

Fucking amazing

[Voldemort1857]

where i can get NaOH

[Templar1974]

Naoh, sodium hydroixde, caustic soda, higly corrosive and must be handled with care. sold in hardware shops for cleaning drains. Is present, in lower concentration, in commercial drain cleaner. I use it in a lot of experiments.

[pkwonder]

not very orangie

[TomIRIDIUM]

It's a pale colour and it's not well visible on screen.

[dpgera]

Nice. I'll try it.
