  • Acetone? I thought Renaissance chemists dry distilled acetates to give glacial acetic acid.

  • 2:30 characteristic green cola?

  • what video do you use this in

  • @mcwario13 I had plans to use it but the use of this is limited. It can be used to copper plate and I think i mentioned this in one of my latest videos. I was also going to show the decomposition of this into acetone but I deemed it to dangerous so plans changed. It can also be used to make other acetates which I may show in a future video. Just mix it with ferric chloride to make iron acetate which again has no real use. It's just an easy experiment for people to try at home.

  • @TheChemlife Acetate =Acetone? Hmmm... Never saw connection before.

  • @99Chemicals it's only minimally produced but it all depends how fast you heat it. ill put a link in the description to a sciencemadness thread that talk about it.

  • @TheChemlife one more question, can i use 100% acetic acid and 30% H2O2?

  • @mcwario13 No for various reasons. One being that acetic acid is a weak acid and actually needs some water to work. Also, i've heard that mixing the two concentrated is a bad idea.

  • what are the toxic gases produced!?!

  • @mcwario13 acetone if it is heated to far.

  • how long did it take you to do the experiment all together?

  • Hey, got no more bubbles but the collor isnt too much dark, is that enough?

  • What's that song that starts playing at 1:25? I've heard it somewhere before.

  • @flarn2006 it's an audio clip from garage band

  • @dang3rousgoldfish Since he only crystallized it out this would be the monohydrate form. To get anhydrous you need to heat it above 100 degrees Celcius. Or you might be able to get it to anhydrous using a strong dessicator such as calcium chloride or magnesium sulfate but I'm not sure about that one.

  • The gas bubbling from the copper is oxygen, not hydrogen. The decomposition of H2O2 is catalysed by the copper ions.

    Nice video nonetheless.

  • @yellowmetalcyborg i know that now but when i did this video i was still new to chemistry. thanks though

  • @yellowmetalcyborg I would think it's some of both. Where do the hydrogen ions from the vinegar go?

  • @flarn2006 Hydrogen ions combine with the peroxide to form water. In order for hydrogen gas to be formed, the metal has to be higher than hydrogen on the reactivity series. The metal has to be more willing to give up electrons that would subsequently reduce the hydrogen ions to form hydrogen gas.

  • Two questions does the copper dissolve ir do I have to take it out and about how long did it take to completely make the solution?

  • turn on closed captions...i lol'd

  • @TheChemlife Hi Dr. Jaaz! I'm 11 but I love your videos and was wondering if I could use electricity as my oxidant instead of H2O2. Like if I got 2 copper electrodes, a 5 volt power supply and vinegar, would it work. Thanks and great video!

  • @Rockflier Yep that would work, it would probably take longer to get a nice blue solution as shown though.

  • Hmmm... your flame test cannot identify the chemical as copper acetate. And what if it's copper chloride, or bromide or any other salt of copper? It will have the same color. You should show a reaction that is only possible when copper acetate is used.

  • i think the gas is actually oxygen not hydrogen. its because H2O2 will decompose to H20 and O2, A more efficient process is using an electrolytic cell with vinegar as the liquid and copper electrodes. check Nurdrage's channel for the set up but he uses H2SO4.

  • wat does this do?

  • @goldedrago it's a colorant for fireworks an can potentially be used as a source of copper or pure ethonic acid in reactions

  • i think the gas is oxygen not hydrogen.

  • Hi, I made this and I think I left it too long that it became green instead of blue. Some site say it is blue green. So you think, why it is green? Does it mean impurity?

  • @Ivanlamperouge did you use pennies or did you use pure copper metal, if you used pennies there is a chance that some copper chloride was formed on the surface and went into the solution at one point contaminating it and making it turn green. if you can use pure copper metal it should help get purer crystals

  • How can I grow crystals from this? 

  • @Ivanlamperouge first allow a few ml to evaporate to form a starter crystal. then make sure the rest of the solution if very concentrated and suspend the crystal in the solution

  • how will I know if my Hydrogen peroxide is 3%?

  • @Ivanlamperouge it should say on the bottle, if your are buynig it from a drug store it is almost always 3% cosmetic stores may sell higher consentrations. in a futur video i will most likely redo this experiment and be more specific as to the consentrations of the peroxide

  • @TheChemlife because I have a hydrogen peroxide which is used as antiseptic. The one for medical purposes

  • @Ivanlamperouge i can almost guarantee that's 3% but it should say on the bottle

  • I LOL'd so hard when I saw the subtitles :D

  • What fuck fuck is up with the subtitles? there screwed

  • Awesome video. I learned a lot. Keep sharing these great experiments :D

  • Much, Much, better than your first video. Continue your working process, if you need any help feel free to message me .

  • NICE VIDEO!!

  • what kind of gasses does it make that are toxic

  • @spotlightman1234 its not so much that they are toxic as much as they are corrosive. even whe i was boiling it down outside somevapour got in my lungs and they were itchy all day. so use either a mask if your outside or just inside a proper fume hood

  • love the new way of presentation :D
