Potassium Permanganate Colour Change (reaction only)

Potassium Permanganate Colour Change - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: • Accidental Reaction - ...
NOTE FROM THE PROFESSOR: The colour change is caused by the purple permanaganate ions [MnO4]- gaining electrons to form colourless Mn(+2) ions. The oxygen from the permanganate and the H2O2 are converted to H2O and O2 (which bubbles off). The extra H atoms come from the sulphuric acid H2SO4. Both the K and Mn end up as sulfates.

Lifelong veteran chemist: "That's pretty cool."
This is why chemistry is the most awesome science

[@Shilag]

And then the professor was scolded for wasting all the permanganate! xD

[@ModestNeophyte]

Jesus turned water in wine, but chemists said NO.

[@Godlim17]

I saw the full video for this. I am glad you shortened it to just this reaction.

[@alakazam7896]

"thats pretty cool"

[@mrericsully]

I have watched all of your videos. I discovered them right before you finished doing the table all the way through and spent the following Christmas break watching them all, but I am enjoying this review.

[@manchesterunited212]

That's pretty cool.

[@alephii]

I love the talks and I do like to review some moments like that. Please, keep the amazing job!

[@HadleyUnited]

This was a hilarious video because the experiment didn't go according to plan, and when this happened, I laughed my butt off.

[@conchamolusco]

this moment was priceless

[@DrLeroyGreen]

@periodicvideos Loving this rapid fire series of Chemistry shorts!

[@Madzarzour]

Chemistry is a wonderful thing.

[@grndmstrjoe]

I might just do that. Thank god for Netflix and Dr Who.

[@dervogelfangersek]

Living this is so exciting! Thank you for all your videos.

[@Zxdfgxdg]

Now, only to explain why a whole bottle of permanganate is gone. Lol.

[@KarlFFF]

Really like the professors happy face at 0:29 :D

[@quinnsq]

I have to stay up till 6am to find out if i've been accepted into university, these should help pass the time!

[@zanzibarland1]

kind of looks like the video is playing forwards and backwards at the point where he pours the permanganate into the h2o2 solution

[@HazMatLabz]

I honestly thought the video was playing in reverse at the start.

[@IAINTAVINIT]

Yeah I've seen all of them aswell.. Was pretty disappointed when I found out they'd all be re-runs :(

[@ragnkja]

Brady, it seems you know us too well. It is incredibly tempting to stay up for the next reaction, but considering it is already past 2 am here in Norway, and I have work "tomorrow" morning, I should probably go to sleep...

[@ChemTechTube]

would have been cool if you revisted each of these, maybe put a new twist on these classic reactions.

[@TomasGrann]

Indeed its pretty cool. Its awesome!

[@IAINTAVINIT]

I'm disappointed.. but 24 videos in a day is better than none! :D

[@Irishkeyblade]

Thanks a million for this Brady, hope you can keep it up! =D

[@renragged]

This video was great. A mistake ended up creating a pretty cool demonstration. :)

[@rageagainstthebath]

Haha, and I'm watching it as I dye my hair violet right now ;) Except I use gentian violet for that. ;)

[@grndmstrjoe]

Damn does this mean I'm going to be up all night?

[@tommos1]

martyn poliakoff, destroyer of permanganates.

[@WeaselWJ]

Fantastic.

[@hellnawnaw]

so you're just going to show us old clips? I expected new stuff :(

[@thresholdofdave]

Is there anyway that this guy can be my grandfather?

[@Melthornal]

Wasted, or made better?

[@ThatDudeWithTheCube]

i think you can do timed uploads automatically

[@Keskivertomies]

Reminds me of Didi Seven, a stain remover.

[@rianneramos925]

Did you mix the hydrogen peroxide and sulfuric acid? :) I'd like to this as my chemistry experiment :)

[@roywastaken]

best of wishes!

[@jelletje8]

but its already 2am here xD

[@brenoakiy]

will you stay awake for 24 hours uploading videos??

[@Mishtkrah]

I didn't think these were going to be repeats. Shame.

[@thekrael]

i saw this before! :)

[@JonathanM-JMart]

pretty cool :)

[@Tininbadoo]

yeah... confused me for a while

[@eugen9611]

it's trolling us

[@MasterAccordionKing]

Hahaha wow. Thats awesome!!!

[@luiserasmo]

where is your god now!!

[@uggles2]

poop!

[@PlayableJackson]

third haha

[@MrGugu99]

second ...shit

[@MegaPanerai]

first

[@conradmward]

That's pretty cool.

[@G0LDUCK]

That's pretty cool.
