Reaction of Calcium Carbide and Water

[rjbatc]

So... I brought some carbide from a visit in a chem factory and stored it in a plastic bag since then. Over time, it went from "stone" to powder. Today I decided to put it in a more acceptable container - I used a baking soda container.

Then I put some of this powder that left over into water and what happened - nothing. ?? Is it possible that ALL of the carbide ( not too little ) decomposed to lime, in a sealed atmosphere (plastic bag) ?

Anyone got any idea where to buy it?

@deathempire70 , can you read? Man wrote:

NOTE: Please don't ask me where you can get calcium carbide. If you really have a need for it, I'm sure that you will be able to find it yourself. After seeing some of the nutty things people do with it, I don't want to be responsible for anyone blowing up their house, or themselves.

Thanks.

i did that when i was 10 using 2 cans covering each other. after i ignite it, the can on top shoot and hit my forehead. sheezz. blood was all over my face.

Used to make explosives as a kid. Put the mix in a thick glass bottle (from floor polish back then) and watch it explode. Good times.

[aimeelovesastonm]

that made ethyne which burned with a luminous flame :D

[suehateu]

it looks like milk.... but it was pretty cool.

[Slashb231]

I sell carbide...miners grade only

Search for 'carbid medemblik' to see the result of our old-year celebration in the Netherlands. Carbide shooting is a tradition over here :-)

[SthealthRaider]

Where u get that carbide

[mrbadx19]

look on ebay, i just got 10 ounces for $10 with shipping. look for videos with it soon :)

[NtlgntNrg]

What are or is there health risks from handling carbide with bare hands? I tried to find out but no luck.

[blueduderanch]

do not touch with bare hands. moisture on your hands can cause calcium carbide with purity above 75% to react. this will product calcium hydroxide and will burn the skin. wear gloves.

[Alex1627g]

im touching some right now.. must not be pure enough. but if you add to water it does the same thing in the video. and smells like shit

[greatwhitenorth112]

nice acetylene

[blackle4ps3]

into any hydrogen making experiments if so might calcium carbide help in bubblier

[flafaloon]

alka celtzer to the rescue!

[kambo57]

hard ware stores or chemical places if they ask its for a school project or for a lamp

[gogo311]

WRONG :D CaC2+2H2O->Ca(OH)2+C2H2

[konobaj]

formula is CaC2

urzicatu: CaC2+H2O=CaCO2+H2+heat WRONG!!! it is CaC2+H2O---CaOH+C2H2

[johnsmith777710]

Calcium hydroxide is Ca(OH)2

[awsomewinecone]

whats the chemical formula

[urzicatu]

CaC2+H2O=CaCO2+H2+heat

[Phillipscreates]

how long does this reaction last?

[minerfrank]

Until all of the carbide is consumed and turned into lime.

[nitrex]

I got some calcium carbide, i had to get a lab order of it. I have plenty of it, about 1 Kg, but i am not planning to sell any.

[OhNoIBarfed]

where did you get it from?

[nitrex]

Chemical suppliers! they supply labs.

[MarryJaneWaston33]

Why didn't it blow?

[EGCblackknight]

The gases weren't contained so it could not build up the pressure to explode. its the same idea as when you mix vinager and baking soda in a bottle. it wont pop unless the bottle is capped so that pressure will build

[magana559]

add bleach to the water and it will ignite on its own underwater.

[kayzixxizyaK]

can u teach me.. how to add bleach into the water.. and how that carbide can really explode underwater... plz..

[magana559]

they are really small explosions that dont even make a noise, just add bleach to the water.....its simple really.

[ChemXu]

you just explained it yourself.... at bleach to the water and add calcium carbide..

[BimotaMoon]

i get it from unitednuclear dot com

[kayzixxizyaK]

haha.. tht would be easily to get here..

[darwinjob]

in old days it was used to produce acetylene for construction needs (acetylene-oxygen burner)

[Syrill101]

u can usually get some in a hardware store
