Chemistry Classics: Acid/Base - Vinegar (Acetic Acid) and Baking Soda (Sodium Bicarbonate)

[liamzuid]

Im going to do this with regular soda.

[HawkPokemon]

i mixed sodium bicarbonate with citric acid

CU Boulder TA sent me here, nice video!

[petgraveyard]

@NiwotCougar1212 That's awesome! I can't believe the traction this video has gotten since I was in high school. Now I'm a TA myself...

[22jagdpanther]

good job :D

[yipfai]

Hi, good video.

I am wondering if we can control the reaction time and the amount of carbon dioxide by adjusting the content, PH value of the acid and base.

I am doing a project that needs to generate alot of CO2 in a short time, do you have any tips?

Thanks buddy.

[ParasDyes]

How acetic acid is used in manufacturing and what are the products can be made through it...this video is really helpful for that .

Thanks. Paras Dyes and chemicals

[NenadE46]

Now Drink it :D

[Rpleech1]

My University of Colorado at Boulder Chemistry 1021 teacher referred us to your video dude, mad props!

[SovietUnicorn]

I can't beleive I was randomly searching through videos during my chem homework and found a video playing my favorite song! I had to stop my music on itunes, because I didn't beleive someone put this in their video!! :D

[rawmark]

Yes, it's also a natural cleaner for gold and silver jewelry as well. Cheers.

[Ianatabo88]

u should put it into a little container with it having a small closable lid and put a small amount of vinegar and put the barcabonate of soda in a paper tissue then put it down and run cose the lid smacked of my leg and i've still got a brooze from about 2wks ago!

[dexodrine]

Awesome, I was watching this to double check the chemistry of this reaction for the use of a poor mans c02 generator. Gonna use a small tupperware (sp?) container, drill a hole through the top and connect some old fish tank filter tubing I have lying around. I'm gonna have the hose run into my badass "grow dome" I have a big clear biosphere, which I am using as basically a mini-greenhouse, I have all kinds of exotic plants growing in there, and I was wanting to boost their growth. THANKS!

[yogiudo]

If you think that is cool you should try this,

heat the vinegar to 120+ C in the microwave. Use a sift for your baking soad and make sure it is as loose as possible. Then make sure the NA2CO3 is spread out over a wide area. Increasing the surface area of the NA2CO3 will increase the area which can react.

Try that.

The hot acid will react 10X better than room temp.

[Slic3R1]

i have 80 % Acetic acid and it is very dangerous because it is toxic if swallowed and if you put it on your skin it will burn you oh and it has a really sharp smell

[vbailey77]

Hey- I'm a 32 year old grad student who was showing my 9 y.o and 5 y.o. and a neighbor's kid this experiment in person and then wanted to explain it more simply than what i could tell them... so i looked for a video and here yours was. Thank you! Not only did you explain the reaction throroughly and succinctly, but you made it very cool in your presentation and at the end encouraged them to keep studying chemistry! Really great!

[petgraveyard]

I'm so glad that you could make some use of it! It was just kinda a fun video that I decided to make on a boring Sunday - I was taking AP Chemistry at the time and had just been doing acids and bases, so it was a nice review. I'm glad you could explain to some future chemists how stuff works - tell them to take AP Chemistry when they get to high school, it really is an amazing and powerful curriculum.

[angeleyes6969]

i was doing this when i was 8, i gets dull quick. try boiling it to create 'hot ice', much cooler. then fill a balloon with the hot ice with a wired up LED inside of it, and make a 'glowing ice ball'

[KatherineNgoNgo]

what song is this?

[petgraveyard]

"The Adventure" by Angels & Airwaves...my favorite band of all time =)

[ironnica]

i expected this to be more fascinating before I did it. Thank god Na2CO3 & Vinegar are very cheap

[petgraveyard]

Are you telling me you actually went out and bought baking soda and vinegar to conduct this rather simple trial?

It's not very fascinating, no, but it is an important demonstration, and one that everybody should see to fully understand carbonic acid's rapid decomposition in air and the basics of an acid/base reaction.

[ironnica]

Yes, i did. Why not? The nephews enjoyed it. It can be used in a few ways demonstration-wise,for gas produced of course. Its boring here in ireland, with high control on nearly every chemical/element thats in any way fun.

[petgraveyard]

Well you did manage to get raw Alkali metals, which I most definitely don't have access to - for obvious reasons.

[ironnica]

thats an open source video that I managed to get to put up. I have done it with potassium but no more. That was due to a teacher leaving the classroom for an extended period untill he saw the "smoke" from afar lol.

[maybelline18]

hey can you explain why the products mass is less than the reactants? I dont quite understand it

[petgraveyard]

The product mass is less than the reactant mass because one of the reactants is CO2. CO2 is a gas, so when you go and weigh the solid remaining, the mass of the gas will not be included.

If you reacted in a closed container, the mass of the gas would be included. In that case, convert the mass of the products to the mass of the reactants using a molar ratio to determine which side has less mass.

[sweetasabunny94]

Wow. That's pretty cool! I need to start doing experiments like this! Except I can't think of anything other than the hot ice with the sodium acetate! Could you give me some suggestions..I'm not that smart.. ^.^

[petgraveyard]

You should take advanced chemistry at your school (that is, assuming you're still in school - if not, or if your school doesn't have it, you could take classes at your local community college for dirt cheap and still get all the experience of a university). No chemistry is that hard if you put your mind to it - once you crack it, it's actually quite simple.

Chemistry teachers and professors are loaded with all kinds of chemicals and substances that would be illegal for you and I to have =).

[DAMNitsvivian]

wow.. that was nice. can i ask you a question though? How can we determine the mass of water, sodium acetate, and carbon dioxide that was produced during the reaction?

All i know is that this is a mass-mass problem..

[deelobrizzown]

So the reaction in a large bucket that is sealed to capure the gas as well.

[petgraveyard]

You would need the molar ratios for the balanced reaction to do that. All you have to do is determine the mass of sodium bicarbonate that you started with, add excess acetic acid such that the reaction proceeds to completion, and then find the mols (then convert to grams) that the specified mass of sodium bicarbonate would produce. Ask your chemistry teacher.

[SierraMoonbeam]

I think that's an adorable way to spend a weekend.

[:

And you totally helped me with my homework. lol.

[petgraveyard]

Please read the explanation before making a comment attempting to "one up" me. I said specifically: "The Na+ (sodium ion) and CH3COO- (acetate ion) are spectator ions in this reaction ..." Those sodium and acetate ions, which you might not have figured out, are the principal ingredients of sodium acetate...however, it does NOT "form." You have to boil off all of the water to get it as a solid salt, otherwise, it's just aqueous ions.

So thanks, I've got that down. Pay attention a little harder.

[H9C101WALRUS]

haha wow zach its taylor

[petgraveyard]

This is the most epic chemistry experiment I could think of with the chemicals I have available at home, what do you want. In school I can conduct small miracles in the chem lab. I made aspirin last week.
