Chemical reactions between metals and water 

For a larger, fresher piece of sodium see ru-vid.comsDgw202LND0?feature=shared

-Sodium, could you stand still for a second? -Na

“These reactions do produce bass” BWWWOOOOOOOOOOOOMWUBWUBWUB

Calcium doing its homework at the last minute.

Lithium is like an introvert taking time to interact (react) with surrounding 😂

most calmest sodium water interaction

"The indicator shows that these reactions are based"

Him: "Let's try adding some potssium." Me: "K."

The reactivity of these metals goes like K>Na>Li>Ca.

Lithium goes "PPEEEEEEEEPPPP" Sodium goes "BBRRRBRRRBRRRR" Potassium goes "BBOOOOOOMM" Calcium goes "MMMHMMMHHM"

Sodium do be giving me DVD bouncing around the screen vibes tho-

"Dude, where's my potassium?" "Gone, reduced to atoms"

Sodium casually making a Bermuda Triangle 😂😂😂

Lithium: Unstably giggling Natrium/Sodium: Bumping itself to the wall Potassium: Burn itself real quick Calsium: holding his grudge too long and just went on RAMPAGE

Li: "mmh.. not bad. Feels kinda comfy in h-" Na: "bro! get me tf outta here!" K: "Nope. I'm out.. peace". Ca: "weaklings..." *Cricket noise* *Intense screaming*

Na : im gonna kill u Cl : so am i NaCl : yummy?

The sodium just casually started forming a pentagram like some sort of satanic DVD screen saver.

Sodium : I'll ruin dvd screen saver's whole career.

*Lithium doing reaction* Lithium: "am I a joke to you"

forbidden bath bomb

*Rubidium* and *Caesium* be like. "I dare you!"

This is the perfect example of how my family react to the same event 😂

"I like your funny words, Magic Man..."

Everyone: Watching all the chemical reactions Me: Watching sodium making different shapes

Damn, these reactions are based

Metal in sodium is like dvd timeout spinning

The metal ball in sodium is living its best life..💀💀

"What did you get out of these reactions?" That I should probably stop eating bananas, I dont wanna explode and Im 70% water

Watching how reactive these elements are. Really inspires the mind to wonder how our bodies developed and what scale. Dna is so small, that when all these metals compile, the energy in them, its much more feasible to see how life starts in an ocean instead of on land.

Been a chemist for a decade, the Alkali Metals never get old.

There's a latency period where the metal takes time to react with the water. I dont know whether the technician dried the metals of their hydrocarbon "shield" before dropping them in water. Also, all of the metlas except calcium floated on water because of their density which is less than water but calcium sank until it created enough bubbles around it to become boyant. The heavier metals tend to be more reactive with water once they get going and that is what we see. Thank you for posting this video!

For anyone who wants to know more, the bases that are causing the dye to change are from hydroxide(OH) compounds of their respective metals (LiOH, NaOH, KOH, and Ca(OH)2) These compounds dissociate in water and split into their ions (metal+ and OH-). the OH- concentration outnumbering the H+ is what defines something as a base. Some compounds dissociate more than others, but from what I know the bases listed here are strong bases making the resulting solution highly basic and definitely should not be touched with bare hands. Anyways if you read this whole thing, study chemistry because it’s awesome!!!

"these reactions do produce base" Based reactions 😎

"The more electro-negative an element is the less it has metallic character" "Electro-negativity is inversely proportional to metallic character " When we go down the group electro-negativity decreases therefore metallic character increases while across the period electro-negativity increases therefore metallic character decreases.Li,Na,k are in a same group and in 2,3,4 period respectively while k and Ca are in same period.So we can clearly say that K will have the least electro-negativity hence will be the most metallic element out of all the four element thats why it reacted fastest. Now if we need to compare metallic characters of other element from the above information we can say that metallic character of Li is less then Na. But how do we compare Li and Na with Ca? For that we need to memorize electro-negativity of the elements. According to Paulie's measurement electro-negativity of :- Li =1,Na=0.9,k=0.8,Ca=1.2 So from the above information we can now arrange them in increasing electro-negative [Ca>Li>Na>k] Therefore increasing metallic character will be [k>Na>Li>ca] and we can clearly see this in the video that K reacted very vigorously while Ca reacted less .

Very nice you put the reactions on the screen to read, because hearing it is really confusing when you’re not a native speaker

-Sodium you're going to lose -Sodium: Na, I'd win

I literally jumped back when he talked about adding potassium lmfao

As an amateur scientists my first thought when I saw the elements was this dude is gonna blow himself up....😂😂

"What u see goin on in these reactions" Me:- sodium going nuts

Sodium just over there casually making pentagrams.

Speed of reaction in the same setup (dropping a bit of each metal in the same amount of water) is what I also observe

I'm learning about the periodic table and gasses ect, and now I get to visually see the gas moving, thank you

If only my chemistry teacher shows cool stuff like this I would be super interested in all these.

Muscle memory kicked in right before I saw that potassium get in the water 😂 I was out the door!

I don’t think anyone noticed but the sodium “Na” is moving in a star shape- 😌 Edit: 1K likes? Holy shi-

Ca was loosing and then it got energy from the power of friendship

You can be anything you want! Na: Imma be a screensaver.

"Sodium, do you like water?" Sodium : "Na"

Thank you for posting this! It's very interesting to see the reactions you study on paper in real life. My school didn't let us perform any science activites so it's fun to see them here ❤️

Thank you for putting the equations on the screen. It such good info for ppl to see and brings the whole experiment together :)

"You hear that fizzing noise? Those are the shrieking eels"

Very nice way to understand about this different colouration of different elements...Lithium, potassium, and sodium are alkali metals .. they are very reactive.. monovalent metal

Sodium bouncing around in the beaker like the DVD logo on TV’s 💀

I didn't knew that calcium reacted in an exothermic manner while in water , thanks for the lesson !

Dude: "now to drop this sodium into the water" Me: "oh fuck no don't!"

Metal (reactive metals)react with water to produce metal hydroxide+ hydrogen gas with heat Ex, Na+ H2O ->NaOH + H2 This reaction in exothermic and base is formed is strong base so it is turning dark blue in colour constantly in indicator

These are Alkaline Metals of Group 1 which have a property to react with water, their reactivity increases down the group meaning francium would be more violent than lithium

When alkali metals react with water, they produce metal hydroxides which are basic in nature

Single replacement reaction.

Metals are reacting with water to form a metal hydroxide and releases hydrogen gas and energy..."is it sir"..and really thank you for this activity..it really helped me..

Lithium didn't want to react but the way this man ignored her, she felt hurt and jealous.

Lithium can actually be “more” reactive when it’s found in its foil form inside lithium batteries.

I wonder why Lithium and Calcium took a while before the reaction was noticable. My best guess would be that these metals formed an oxide layer on their surface, which first had to react away before the metal itself could react with the water

Potassium always wants a quickie but a blast.

Never seen fire under water before. Very cool

These reactions are exothermic... especially the with k... it's highly exothermic 🔥

Learning so much more from RU-vid than I did in high school

nice demo! no explosions needed. I like the sodium scooting around like a boat.

I hope my bones don't randomly ignite

I was disappointed when I noticed that the label was "Ca" instead of "Cs"

Observation: water got mad, now blue

Man, Peter Griffin knows his chemistry.

Its 100× more fun to watch after studying these reactions from books and finally seeing them happening Is truly marvelous, is that dye litmus one ?

Crazy video! Keep it up!

as a chem nut, the way my heart dropped when i saw potassium was on the list 😂😂😂

This is why they called BASED metals

"Next we'll add some Francium into the wat-"

Very good idea to show all together . All the best for your content.

Finally something we don't waste the internet on

To those who dont know, its not just a regular dye. Its called an indicator

I legit thought one of these beakers we’re about to explode and was worried for a second

"and these reactions do produce bass. *epic dubstep drop *"

What was up with that lithium? It usually reacts faster than that.

Bruh i really like your videos they are so satisfying ❤

Due to lockdown i didn't get to study analytical chemistry properly, thanks for showing the reactions!

My first thought "he's got the wrong symbol for Caesium. And he's gonna get a shock when he drops it in!" Turns out he *does* know some chemistry going in.

"You hear that fizzing?" "It means by bomb is preparing to explode! Isn't that cool"

The electrostatic attraction within the calcium atom is stronger than that of potassium’s. Calcium sinks whereas the alkali metals float. More questions come to mind than answers. Excellent demo!❤

And this is because they are further down the group . each time you go down the group , the reaction is more reactive than the last

Him: Calcium reacts with water Me: *proceeds to add milk in water 💀*

When you paid attention in chemistry and see this : 😨

Need more videos like this, thank you very informative

I guess you could say these reactions were based 😂

- The Universal Indicator transforms into a blue colour to indicate a basic/alkaline solution. - The Hydrogen in the products becomes Diatomic Hydrogen due to being extensively reactive. The Lithium, Sodium, and Potassium Ions all have a charge of positive 1 due to being cations - elements in group 1 which lose Valence electrons to gain a complete Valence orbital shell. Due to the addition of electron shells from Lithium to Potassium, the core electrons are increased, increasing the shielding between the core electrons and the Valence electrons. Thusly, the electrostatic attraction between the nucleons and the Valence electrons is decreased, making these elements more prone to losing electrons. For Metals, reactivity is measured as the tendency for an atom to lose electrons. The reactivity is increased as you move down Group 1 due to to the addition of shells, shielding, lower electrostatic attraction between the nucleus and the Valence electrons, and the decreased Ionisation energy required to lose electrons. As for this reason, the Electronegativity of the elements is reduced as you travel down the group. The entirety of the aforementioned excludes Calcium+2. Due to the increased Reactivity, this is why Potassium was the most vigorous and reacted the quickest.

Exothermic reaction🙃

Why is this so satisfying

Ah yes, my favorite metal Calcium.

Lithium is the most electronegative element but yet it shows less reaction with water because of the High Hydration Enthalpy due to its small size. But the Sodium is the least electronegative element in 1st group elements. These words were written in my chemistry school textbook , but I still remember it 😂

Observation: Calcium is floating on the surface as it reacts with water to liberate hydrogen gas . This hydrogen stick to the surface of calcium thereby making it float

sodium + water made me try backing away from my phone thinking it would protect me from a pre-recorded explosion.
