Yeah, your "water" is a real chemical.

[MrLol333]

it's a redox reaction. the hydrolyzed sugar reduces the permanganat ion in alkaline environment in the first step to the greenish manganate ion, then it further reacts to manganese dioxide, which is the yellowish colour. But in a acidic environment the permanganate reacts to the colourless Mn^2+ ion.

[nosyarlin]

how long does it take to change color?

[JerryGiesler09]

For those who think this is fake, It's NOT the led's that's changing in color. It's the solution that is changing in color.

[YOUTUBTHAN]

let me ask you something.... you say to add some sodium base... can you tell me if sodium acetate would work as well????

[Fifaboy5433]

@YOUTUBTHAN sodium acetate is a product of salt and vinegar so no, you should use NaOH (lye)

[melnadiacillian]

@Fifaboy5433 you said youtubthan was wrong but you are wrong.you get sodiun acetate when baking powder and vinegar are mixed.you just try mixing salt and vinegar and make hot ice.no dont.it does not work

For the first 1.20 min I thought that is instruction "How to prepare tee on your own"

[Swizz884]

Интересно : )))

[Billybob9601]

Sometimes when people do these kind of things without a real explanation, I think they're just changing their lighting

cocky

[thebigtfan]

How exciting!!! Next time, we can watch grass turn from green to brown as we don't water it over a period of thirty-eight days. (I'm getting goose-bumps with the antici....... pation!)

[Mauritan]

thats from a tornado lamp!

[imnicebutheartless]

is this a redox reaction?

[haku0103]

i kinda get the idea of this trick...since the color only ranges along the blue region, maybe this experiment took the opportunity to use the changing basicity of the mixture and used KMnO4 as a color indicator...the thing is, I still can't figure out why the mixture changes in its basicity, maybe due to the sugar's oxidation rate?

[flarn2006]

You can buy KMnO4 at Petco. They sell it as Jungle Clear Water, in the fish department.

[Juggarnort1]

I trid to do it myslff but something went wrong and mine was just funny looking water :)

[MrTimoteo1596]

i went to purple to blue WOW boring

[Mynolupo]

ahahaha this is a ph turning point experiment

[nickmt]

Ah yes can see why you might think this is a pH changing experiment :D ... but it is not.

The colour change is as due to the reduction (gain of electrons) or change in the oxidation state of the Manganese ion.

1) Purple --> Green is due to the reduction of the Manganese ion and the oxidation of the sodium hydroxide.

2) Green --> Red is due to the further reduction of the Manganese ion and the oxidation of the sucrose (sugar).

Hope this helps

Sugar+NaOH and KMnO4

[ahmed4013044]

what is the mechanism as purple color of KmNO4 discharge in acidic medium ??

and he add NaOH that is alkaline so medium became neutral or basic ????

[inphantzz]

Never Knew Potassium permanganate existed in liquid form! :D

[ahmed4013044]

found in liquid form and have deep purple colour :D

[TheFluorineMartyr]

Found as a solution, it has a deep purple colour.

Many salts dissolve in water!

[blueduderanch]

my god.........

[nickmt]

I imagine that this is a pre-prepared solution (water + solid dissolved) of KMnO4 :D

[YellowCakeKid]

why is ur water brown

[BozhidarStefanov]

@YellowCakeKid Because I live in Bulgaria, duh....

[kougsohv9]

one of my favorite reactions! NaOH os available at most hardware stores!

[fetrug]

Amazing vid!!!!! =)

[omeganet05]

Pretty cool ;)
