Chemical Reactions

[team0switzerland1]

we did a experent like that in school but we got to explode a tiny test tube to get silver from copper

ps this is SHIT

[arikim]

I can't fap to this...

[MultiKenny64]

@arikim wtf

[liamzuid]

What other elements ''want'' to get negatively charged?

[Dark3000Iight]

copper + Iron III (ferric chloride) = combustion

[perkleiven]

what happens if i drink it?

[bacon75334]

57 people will never be a scientist, they will end up as a lollipop man

[dhartpimp]

is observable a real word?

[dhartpimp]

dude that is CRAZY

[Achilliez101]

the colour change from clear to...... *slowly puts metal back in* lolololol

[JerryGiesler09]

Free silver!

3:28 Lead Chromate + Potassium Iodide= Potassium Chromate and Lead Iodide.

[ajkeel]

@JerryGiesler09 only that getting the potassium iodide and lead chromate would cancel out the money you make from the silver xD its not very profitable

[JerryGiesler09]

Free silver! :DD

[BambooDoodle]

What does he say at 1:23?

"The blue colour of the solution is .... of the formation of the copper nitrate solution."

[nikta10]

@BambooDoodle indicative

[chemsnippets]

@BambooDoodle "indicative" as a way to say it indicates that copper I(I) ions are becoming dissociated in the solution, making it appear blue, the negative ions also dissociated in the solution are nitration ion which are not causing any color.

[Pongskiez]

Thanks a lot ! ! ! !

This really helped me in my chem.project !

[ramiabuhamra1]

thanks this really helped me in my science project for school

[Nxcng]

i think i could make a better video ...

[privsharps]

the last experiment was dumb in are ap chem class we do it with 30% peroxide and not this shitty 3% he has and it makes a huge smoke ploom like say a Jeannie out of a bottle

[DOUGIEFRESHENz]

@privsharps I honestly don't believe that you're in an AP Chem class considering your disgusting spelling. Anyone who can't spell "our" should never be allowed into ANY advanced class.

[syedjaafar]

nice nice...

[DynastyPercussion]

By the way you should try to run a car with some of that stuff =P

[DynastyPercussion]

Just add a non-colored thickening agent to it, hopefully it doesn't explode lol, and you got yourself Grunt's blood. Without the glow.

[XBOXGAMER269]

rubish



[emokidk2]

drink it

]

[sonnyandantonio]

im studying this at school I HATE IT I DONT EVEN KNOW WHAT HE IS TALKING ABOUT

SOUNDS LIKE MY TEACHER

LOL

[rudmop]

@sonnyandantonio you may wish to study something more simple; I would not advise you to go make insulting statements in such a public forum. It shows that you are unable to listen, learn and lack the desire to learn and maybe even lack the intelligence for such a rewarding subject that few people on this earth come to understand

[sonnyandantonio]

@rudmop mate i dont mean that

by the way could u help me

why does a rainbow appear from a reflection

[Dragonspirit999]

3 words : COKE AND MENTOS!

[SevenfoldSam]

is that silver worth anything?

[IamSnozzler]

@SevenfoldSam It's probably worth a good bit less than the solution he started with.

[CarlosFontal94]

thanks for video really helped me with homework =D

[Melini02]

one question... the hydrogen peroxide combines with manganese dioxide and forms water and oxygen gas...what about the manganese...does it stand by itself now?

[ggglllllll]

cool

[mustafa233465]

he is becoming rich by taking the silver

[Shadowmov3r]

That was really interesting, I mean it.

[normalboy64]

this is boring!

[Shadowmov3r]

@normalboy64 Then go do something that's less boring, maybe a realization course, so that you realize that something is boring without having to watch the whole video.

[TheIdilAli]

can anyone tell me what the single between sing and doubble displacement is. Please email my youtube account ASAP if you know THANKS

[PurexOvvnage]

it's the same color as the statue of liberty

[MrHarry46]

so how do you get the copper out of the nitric acid now

[Plibt8]

i've been looking everwhere for an exact description of the chemical reaction of nonoxynol-9 (spermicide) and sperm and how it works but i keep getting directed to teen websites and planned parenthood sites T.T

[IAMBILLYTHEKID]

Ever seen a molecular change? Type White Gasoline Vapor, here. Read everything, including comments, and you will see when I discovered I had preformed a molecular change.

Bill

[cutenukkah]

so this is real silver? like jewelry silver

[joshgibbs69]

Yes, it is real silver

[markthe5hark8]

whats the chemical formula for hydrocarbon ?

[NewBornAssassin11]

A hydrocarbon is CH,3 part of a methyl group.

[mattmax11]

is the powder on the last experiment the stuff they use for flash paper

[TheAndrewlaw58]

OMG ITR SOUNDS LIKE MR. ROGERS!!!!!

[ChickenClaws]

Hey...i just did the Hc and zync experiment last friday in chemistry class haha.

[1jaime2222]

cool i love chemistry

[BoTheCrazy]

boring... I know definitely a funnier way to show chemical reactions.....

[VampireKyou]

why don't you give us an example by dipping your hands in sulfuric acid?

[baconator490]

sulfuric acid isnt that deadly, it would just be small burns

[Danielst16]

I don't think I would have made a video of these reactions, not exactly spectacular are they? I have done pretty much all of these in one way or another. The only difference is we didn't use silver nitrate and a copper strip, silver nitrate is too expensive. Still some of the most boring experiments I've ever done, sorry but it had to be said. Saying that learning the science behind it is still awesome.

[tomguelph]

so copper in the lovster blood explains why it's blood is blue

[tomguelph]

E-bay

[jeepman787]

a month ago i could have explained every detail of what is happening down to the electron configuration to the percentage yield

but alas its summer

[TheMoni286]

so... i can replace the pure silver in the silver nitrate with copper and produce pure silver? if yes then why not sell it?

[buckles75]

The answer to your first question is 'yes' because copper is more reactive than silver. You can even use a cheaper metal like aluminum or iron to displace the silver. As far as selling the silver goes, think about how the silver nitrate was obtained in the first place. It's not that cheap, and you have to also absorb the cost of the metal you're losing into the solution.

[ronaldoandiverson]

wat kind of science is this..? is this physical science?

[TheMoni286]

the title is "chemical reactions" so what do you think it is?

[11to]

were can you buy HCl?

[WTFClock]

from mah pocket.

[Chemateur]

I got a quart of 31.45% HCl at Ace for like, 3 bucks

[HaRuKaSaN1234]

AWESOME!!!!

[Lawetzwtf]

ye, but the silver you're probably thinking about is the kind of silver that makes your eyes sparkle with dollars. The process of making silver-ions into a solid silverplate is more costly than if you buy the plate at your local merchandiser :)

[cupwithhandles]

can I use this info to pick up nerdy chicks. I think so.

[h16a3]

good

[sodexho13]

waste of time

[chemsnippets]

Boredom is an insult to one's own-self.  Try educating yourself a little and stop being a scientifically illiterate bum.

[hokageninja9090]

Hmm...no I'm gonna play halo now.

[WTFClock]

lol

[vhyom94]

i agree

[brokentoedspoon]

@chemsnippets Yeah!

[Theprophet524]

is this an example of the law of conservation of mass

[Lawetzwtf]

I'm curious too.. somebody please reply :) (taking that you know it, of course)

[stefsue6]

If you want to take it that way then it can be. Matter is created nor distroyed and nothing was destroyed in those chemical reactions. If you do a chemical equation then the reactants should be the same as the products when balanced.

[mbuzzby]

GAY

[JakobHarquail666]

I have a few questions

In regard to the first chemical reaction; can this mixture of copper and silver be used for anything in particular?

[devinhesterowns]

LOL.. you got ripped off!! you paid $50 to watch this video hahaha!! Oh wait this is a youtube vid.. its free.. Quit Complaining!

[willdawg840]

still a shade of blue..

[PyreX9]

The last experiment, the one with the powder.

What powder was it? Was it spores from the plant Lycopodium?

Yo should try that =)

[dragonridley]

I remember using a catalyst with hydrogen peroxide. We used catalase.

[canadionsoldierboy]

for the first one...it makes it better with a copper spring...but all in all its a nice video

[sweetandsexy909]

It makes sense now! Well for the most part.;)

[whitty2350]

You need to have chlorine atoms present in one of the reactants to make it as an element. berk.

[purplep0wnies]

noob

[holymonkey3]

2nd experiment: you should have used magnesium, bubbles like hell!

[LilOne9290]

i did this in chemistry today lol but we used copper (II) chloride dehydrate instead

[acount134]

ok please!!! help me i mixed h202 Kno3 and citric acid and i put a carbon anode and an iron cathode. it started to bubble and i thought o neat a fuel cell. so everything was cool until it turned yellow i thought O NO CHLORINE!!! so i quickly took out the anode and cathode and took it outside to examine it IT WAS STILL BUBBLING!!! i saw fumes coming off and it was no brown and a white percipitate PLEASE TELL ME WAT I MADE!

[Mekill60]

Lol, none of the compounds you dissolved has Cl in it.

[drpepperpepsicoke]

science is cool

[fuukenstein]

i am woking on ion replacement with rhodium,platinum and gold. any ideas?

[polopol9]

hey,wat up,nice chemical reactions

[10243406]

nice! thanks for the clip , wanted to see displacement reactions in action.

[sonicsecrtrings]

err did you spend loads of mony to show us that?

[jackomite2]

please excuse my friend DurasDrums. hes just trying to tell you he has no friends.

[DurasDrum]

Please excuse my friend paulkuijpers, guys. He's basically trying to tell you all that he's a dumbfuck.

He does that often.

[MissKriss94]

lolz

[freakykris2]

my brain hurts now =(

[v3user810]

today is 24.06.2008 1USD=1.26 BG levas

100 g silver nitrate => 70 levas (=55.5 USD) it is so expensive like all other chemicals in Bulgaria

[HotRockzz]

Is it possible?

[james99xh]

intersting

[Yukwaz]

n=m/M

[gukako]

I win MYT COMENT HAHA

[gukako]

HOW DO YOU CREATE FIRE ?=

[seggsygal2]

wow..expensive stuff poured into the beaker..

Silver nitrate is expensive in my place =(

[XheartXofXmineX]

sience uses expensive metirial.

[SiiKESTSHiiT]

DAM STRAIGHT HE IS.. LOL

[rugbypro46032]

lil wayne is da best rapper alive

[beans4444]

god im bored how, its bad that i have ended up at this video

[danngree]

...to bad silvernitrate is like 3x the price of silver. or id set up a bathtub full and grow my own silver lol

[simpsonstewie]

okay.

[2882890]

Take this as an example: I have an interest in Banjo and bluegrass music. I'd say some people who look at this video do too but most don't. Can I force uninterested people to want to know about Banjo and bluegrass music, and whats more to like it? No! But we do this to school students everyday and just think to ourselves "they're too stupid to know what they like anyway".

[Yamakiri]

Well what if the students think this is cool/fun? Also, why are you watching this if you find it boring? Why not watch more bluegrass banjo music? (No offense to them, 'cause bluegrass is cool) My counterpoint is that the students need the knowledge to make the most of their future career and lives.  Science is a good career too, so just because you don't like it do you think it should be pulled from the school system? The answer is no. But I will admit that the faculty think they're gods..

[2882890]

From the comments I'm reading on this page it's not cool or fun. Why am I watching it, well I like science but I don't particularly the way this video tries to show science especially to young students, it's too technical, not explanatory enough about the complex things. It might be fine to a seasoned university type but young students won't enjoy it - they'll put up with it.

[heloimutube]

I hear a fog horn....BOOOOOOOORRRRIIIIIIINN­NGGGGG!!!!!!

[OGMO11]

I hear a baby cryyyyyyyyyyyyying (referring to you)

[nintendowns]

chemistry owns, fluoroantimonic acid:)

[smigasmithy123]

if you was a teacher i would fall asleep in your leasons

[Balloonist14]

...maybe that's your problem

[2882890]

I wouldn't agree with you. This is a scientific video only for those who really are interested. But most science teachers are like this (mine was) and most students have no idea why this is supposed to be important to themselves especially when they hardly understand whats going on. It's too technical. It's like someone showing you a quadratic equation and expecting you to be interested when you've no interest or can't find it useful.

[easyas4]

chemistry can suck my balls, i have done one lab in chemistry that was cool my whole year, if you dont have to take it, DONT!

[RatkoUSA]

Ok, that's all interesting and stuff, however, students most likely would be more inspired and eager to learn if your demonstration involved more practical and useful chemistry they could apply to everyday situations in the real world. For example, something like an industrial strength fart bomb, or perhaps an oderless colorless psychotropic gas. At the very least something that blows up or bursts into flames. Ya know, the kind of stuff that makes young people say "Holy f**k chemistry rocks!!"

[f22pilot2]

ooh powdered hydrocarbons if im not mistaken all that means is ground up and possibly treated plant matter

[AlfaTampio]

Duh so amazing.... -__-

[lumpfish99]

frosfrate my prostrate en fosty nnn ig oh I cant take it !!!!!

[starrynight594]

i hate this video!!!my science teacher made us watch it in class..u should feel special chemsnippets

[notesoflecture]

percipitate IS the solid!

[getmewild]

I always hate Chemistry but this one is cool!

[jwmvb]

lol

the last thing is so simple i do that whit powder sugar, just take a candle set it on fire:P and let the powder sugar vall from above on it not to much becouse that wil kill the flame but neather be scary becouse when you wont drop enove it wil neather burn

[Baltican]

This is so like... blabla bla copper bla blablabla hydrogenbla bla blablabla blabla oxygen.

[starrynight594]

lol i agree!

[yolshian]

lol thats hilarious!

[kingkongo101]

I <3 chemistry

[davdd69]

"this is why a silver precipitate forms"

silver precipitate? no, its just solid silver, precipitate is when you combine 2 salt solutions where displacement occurs and one of the product salts happen to be insoluble in the solvent

[ZildginVicFirth]

and you shake it onto your fries and then you don't have to ask for the manager to complain about the bland tast.

[chemsnippets]

when silver is a dissociated +1 ion it is aqueous and is dissolved. When it reduces to a neutral atom with a 0 charge it falls out of solution as pure silver; this can be to say the silver precipitated out of solution as pure silver. In a single replacement reaction the precipitate is usually a pure metal; sometimes gases can be evolved. In a double replacement reactions, the precipates are salts as you have mentioned.

[pearcey77]

indeed.

[askaninjafan]

lol

[SanandreasMythBuster]

All Smart lol!!

[cottonkandynb]

Hey we did these reactions and more in chemistry class! Cool video. :)

[11vvdd]

I had to do some of the double-replacement metal ion reactions along with others in my lab. It was interesting, lots of colors.

[qaz8921]

are you stupid or something?

u just don't get it!!!

[studom]

there is no need to speak such language, remember who uses this site!

[Gixbit]

retards? self-important losers? wrist cutters?

Or are we talking about kids?

[gymanast84]

thats awsome!!!

[ayiy2]

OMG this man is soooo boring he could bore pplz to death im glad he's not my science teacher and oh also... an awesome lookin rxn is wen u burn a magnesium strip and it burnz in a white flame it looks awesome but dont look directly into the flame

[qaz8921]

this video is interesting not boring!!!!!!!!!!!!

[drummerforpeace]

yeah time lapse would help.

[poohbear5050]

2 words... TIME LAPSE

[kaizerxv]

Good idea, then we could have seen all stages of the expiriment.

[Mythtern1]

I made a penny look like gold in science last year, it's really cool!

[jack6565]

i was thinken why copper??? then i relised the displacment stuff haha,would of worked better with platnem (if you are rely into this stuff) and silver nitrate. i think... donno year 9 sciance.

[saxamaphone20]

Probably wouldn't have worked. I think platinum is lower on the Activity Series than Silver is.

[jack6565]

yea rong way round haha,

[TheScythe217]

could be a little faster lol

[Hermione77777]

I would like to know more! I was expecting to click on sruff like baking soda and vinigar or coke and mentos but....Yours is way cooler!

[vibol03]

wow thats dangerous but cool!

[hboy007]

not dangerous but expensive ;)

[jenny911]

Cool...!

[youkickedmuhdog]

do something else like that!!! just without the hard words haha

[rovero]

the last reaction looks like the same reaction when u drop coffee creamer above a flame like that

[30GB]

i did the same stuff in class in grade 10
