Potassium - The Active ALKALI METAL!

Please note that this video was made solely for demonstration purposes! Do not attempt to repeat the experiments shown in this video!
So today I will show you a few experiments with a very dangerous and expensive metal - potassium.
Potassium is an active alkali metal, which is in Group 1 table of chemical elements.
Compounds of potassium are essential micronutrients for many living organisms. Pure elemental potassium was obtained in the early 19th century by an English scientist.
On the appearance, potassium has a metallic luster, with a slightly bluish tint. It is a very soft metal, about as hard as the butter from a refrigerator.
In air, a fresh slice of potassium is being instantly oxidized and coated with a layer of peroxides and carbonates. Potassium is more active than sodium.
So if small pieces of sodium react with water more or less calmly, even small pieces of potassium immediately ignite and explode spontaneously.
The reaction of potassium and water produces alkali, and hydrogen is released which burns pink flames due to potassium ions.
In the slow motion shot you can see how hydrogen is ignited by potassium sparks. The behavior of potassium in the water is very unpredictable.
Even small pieces can explode in water powerfully, although on the contrary large ones do not want to blow up and instead they just burn. Do not attempt to play with potassium, it is very dangerous!
Because of its high activity potassium may spontaneously ignite in air. I took a small piece of potassium and began to spread it on a napkin.
Once the napkin is coated with a thin layer of potassium, the latter reacts with oxygen and ignites, thus potassium superoxide and potassium peroxide are formed.
Also, for this reaction a napkin is involved. Because of its high activity, the potassium can pull oxygen from the cellulose molecules that napkins are made of.
Potassium can be set on fire, it will burn and form potassium superoxide. If potassium superoxide is dipped in water, it will begin to decompose into oxygen and potassium hydroxide .
In the last experiment, I took a small piece of potassium and threw it into a cup with ethanol.
Potassium rapidly dissolved in ethanol to form ethanolate, potassium and hydrogen.

[@myell5735]

I legit looked for this video after playing the game, got curious somehow

[@matthewcowell]

I wish you did more elemental properties videos like this. They are very engaging and informative.

[@Nathiusca01]

nice, it looks satisfying when you cut the metal, I want to do it :)

[@jeevanimmanuel8806]

yeah😂😂

[@aapeli4824]

you can even bite metal called indium, I recommend it because indium is a lot safer

[@agirlisnoone4852]

I searched "cutting alkali metals satisfying" and this popped up

[@uxleumas]

make sure to not cut old potassium. the superoxide is on the outside will get onto the inside and react. (basicly, u cut old potassium, stuff catches on fire. you could try lithium but still be careful) wait... why am i even replying to a 4 year old comment

[@siyuyangzhang6995]

I also try to do the reaction of potassium metal reacts with the 96% ethanol (contains 4% water?), the reaction is too violent that can easily ignite the ethanol; when I try to reacts potassium metal with the 99% isopropyl alcohol, which is less reactive than ethanol, the reaction is much milder, at moderate level similar to sodium reacts with ethanol, the isopropyl alcohol never ignited and the potassium metal even not melted, which is much safer. While sodium reacts with 99% isopropyl alcohol very slow, can takes up to several days for the reaction to be completed.

[@zachell1991]

would it be more reactive in hydrogen peroxide(H2O2)? would be cool if you made a video showing the reaction.

[@aishibhattacharya7044]

Wow what a reaction

[@frankknowlton736]

Great video Thoisoi2! By the way, ethanolate is more commonly called ethoxide.

[@elephystry]

Felix Jin In English, yes.

[@vishaljaiswal4777]

Amazing

[@unbrokenriven1455]

when the potassium went underwater it had no flames on it. so, what will happen if you perform the same reaction but keep the potassium underwater? and what will happen to potassium if you put a coffee filter before throwing it in? will it become transparent like sodium?

[@siyuyangzhang6995]

What is the purity of ethanol that you do for potassium metal reacting with it? Is it at risk that potassium metal may ignite the ethanol? What to do if the potassium metal ignite the ethanol? Thanks.

[@Russianbro777]

My potassium metal set off like a fire work than kept going, it stuck to the beaker and gave me another surprise.

Kazakhstan number one exporter of potassium

Thoisoi is not from Kazakhstan, which makes me suspect that he is using Inferior Potaeysium.

[@marcosvieira2615]

Doubt: In you transcription you said: "Potassium rapidly dissolved in ethanol to form ethanolate, potassium and hydrogen" but in your speech you said: "...dissolved in Potassium ethanolate and Hydrogen".. Which one is correct? :P

[@enderasu]

To most of us who flank chemistry this is magic. Enjoy!

[@allamreddy4744]

Potassium cannot be kept under?

[@ibrahimbakrc5903]

I don’t understand that why potasium oxidization create KO2 Because potassium has a 2)8)8)1 electron sequence and the chemical reaction must be occure that “2K+1/2O2>>K2O” isn’t it?

[@carsonmclean9810]

Question was that equation equal on both sides

[@damonjackson5857]

Carson Mclean yes because potassium "wants" to stabilize itself

[@Taki7o7]

00:57 I'd call it Satans Metal, look what it draws ^^

[@hunterboyvids]

Will potassium go transparent like the sodium did?

[@Thoisoi2]

+hunterboyvids Yes, howewer, the transperent droplet is a hot potassium hydrodixe, not transparent potassium.

[@origamigek]

How do you know?

[@JerryGiesler09]

+origamigek I suspect that the potassium was liberating yet potassium ions into the air. The hot droplet leftover from the reaction is potassium hydroxide. How it float is from the Leidenfrost Effect. Same thing for "Transparent Sodium", but with potassium the duration is shorter.

[@MrPyroguy1]

+origamigek He doesn't know.

[@oxm18]

So you could make bullets with potassium. Doey it explode on impact?

[@Kargoneth]

The Combine are coming!

[@Elsutochanh]

2:59 Wait, K + O2 = KO2?! (thought it was K2O)

[@notanuragg]

Late reply but, K forms a Superoxide when reacted with oxygen (a single negative charge on an oxygen molecule) hence forming KO2 as opposed to K2O

[@Barefoot0Walker]

all of the group 1 metals react with water and ignite. the farther down the group you go, the more powerful the reaction. cesium will explode on contact with the water vapor in the air! in a normal reaction, four k plus one oxygen molecule make two k[sub2]o molecules. but the reaction documented here is one k to one oxygen molecule and you get ko[sub2]! that much extra oxygen would have to be a super-combustant!

[@HiOwl]

Potassium react with oxygen gas isn't that 4K+O² ->2K²O?

[@JG-dt2ub]

It made a star at 58sec

[@oxm18]

Can you tell me the name of the element that contracts on heat and distracts on cold !!!

Gallium?

[@nimnimlight]

[@whatelseison8970]

I want so see someone burn potassium in ozone and then characterize the potassium ozonide. You up for that? BTW, C2H5OK is potassium ethoxide, not potassium ethanoate.

[@szymonsiudak916]

3.00 Small mistake it should K + O2 ---->K2O

[@larrytischler8769]

He said heating the potassium metal in air made the peroxide. Several references say K2O, K2O2 and KO2 are formed.

[@antetal9348]

If sodium reacts with water calmly? Larger pieces of sodium react with water more spectacularly than larger piece of potassium do with water.

[@nguyenkhoa137]

wait ! is KO2 right? I thought it was K2O

[@elephystry]

Khoa Nguyên I think ko2 is superoxide, and k2o is oxide.

why should i not repeat i'm a explosives guy

KO2??? It is not right equilibrated. Maybe K2O or K2O2

[@undeclaredvariable4057]

KO2 is potassium superoxide: K+ and the (O2)- anion

[@sircakington8409]

isnt that stuff radioactive ?

Sir Cakington Francium is. I'm sure there are radioactive isotopes of potassium, but not all isotopes are, if so.

[@zainnguyen2137]

3:01 You mean K2O right ?

[@OnamKingtheKing]

he said superoxide, so KO2

[@hijamsangbanabi4126]

Haha I want to eat pure potassium

[@andrzejurbanczak4868]

4K + 2 O2 -> 2 K2O Cause K is in the first group

[@luisillo3511]

Yes, but potassium can also form peroxide and superoxide, and I think he was showing the reaction for the superoxide
