@@alexwang982KMnO4 is a catalyst, here as an oxidizing agent, so when the reaction takes place it doesn't directly take part in the reaction but helps in it. After the reaction, after some time KMnO4 comes again to it's original form, hence can be used again and again
This is pretty neat but it would be nice to know all the chemical reactions that occur, for example, why does the solution turn colourless when heated? And are the bubbles carbon dioxide or simply steam?
The ethanol is getting oxidised to Ethanoic acid with the help of the purple colored KMnO4 sol., and hence, the KMnO4 eventually gets reduced to MnO2 which is the brown deposition at the bottom of the test tube.
@@rawgauravpandey The thing I learnt in my chemistry class last year was acidified potassium dichromate. Alkaline potassium permanganate wasn’t on the syllabus.
@@rawgauravpandey I do remember using potassium permanganate, but acidified, for oxidising iron (II) to iron (III). This is part of finding how much iron there is in iron tablets.
I thought an acidification step was also necessary? Bc in orgo we write something like ethanol -(KMnO4 over H+ arrow)> acetic acid... does your method here work just as well and if so isn't that more efficient?
Cheers Bro its examtime and it helped me a lot
How was your exam? 😂

apparently it has something to do with sulphuric acid in that solution
@@strikex9543where in the world is sulphur coming from

@@strikex9543Don’t they Alkaline potassium permanganate for this experiment?
Hey.. this is cool.. I am gonna use your video for lab presentation. Thanks a lot :)
Where is the brown precipitate
Why in first step he added Kmno4 with h20 if he has to add it with ethanol ....do he used that Kmno4 with water in ethanol in 2nd step ???
He showed that he is not adding KMno4 in water in the 2nd one
love the background music 😆👌
You could also add acidified potassium dichromate to the ethanol, and reflux it.
The observation is orange to green.
what about alkaline KMnO4 ?

@@DaveDVideoMaker well both are strong oxidising agents.

Why didn't you use a reflux condensation rather than heating directly?
Good bro 😄 , I am from India

acidification is necessary when potassium dichromate is used as an oxidation reaction. potassium permanganate needs to be alkaline.
Is both the potassium and the ethanoic acid at room temp when added together?
Temperature here doesn't matter ,I guess..
This was such a beautiful reaction
why is the background music so sad
Open flame to warm alcohol? Do you want to get an explosion? Because that's how you get an explosion.
Nice music though.
Dude, beer is like 5% alcohol, the guy is using pure alcohol.
Dude, ethanoic acid is not alcohol. Not is it flammable.
Leo Brazz
It is an alcohol.
@@dt3042 no ethanoic acid is not alcohol
when adding KMnO4 into the ethanol and turns to brown colour it already changes to ethanoic acid.
Does the ethanol need to be anhydrous?
Thank u so much for this video
really nice
You can collect hydrogen gas na ?
what happens to kmn?
Thank you for the video
Very good, thank you!
What is the colourless sol formed
Ethanoic Acid and Manganese(II) ions
what about the potassium?
The potassium is a spectator ion - it doesn't change at all.
So is there still potassium ions floating around?
Yes
❤❤❤
Why the brown color is appear???
Mn7+ in KMnO4 gets reduced to Mn2+ in MnO2, the brown colouration is due to Mn2 formation
Thanku very much 😊🤗🙂
Do u use social media
Sir devi tr ne bheja
Without equations!!!!
please help , somenone makes me learn chemistry and i do not want it:(((((((
not bad
Hi
Why is this yll😕😲😤😬😈😱😨
