    Hey there, just wanted to say thanks for making this video! It ended up inspiring a large segment in one of my videos about building Spider-Man's web (and how diy polymer production isn't actually the ideal solution haha)

      Hey man i came from your video and i have a question, yeah maybe rayon is not a good idea but did you checkout PMMA web fluid? the human spider , the.amazing and other spider people are developing a formula based on that.

      Vidushi Gupta Don't wait for the cotton to dissolve. Keep stirring the mixture using a glass rod. The mixture will become pretty viscous but it can easily be sucked using a syringe.
      All the best for your practical!

      Basically Rayon can be obtained in 2 ways, viscose method or the cuprammonium rayon that is being discussed here.

    If I read right, the threads can be dissolved in Carbon disulfide for a stronger product.

    IS IT NECESSARY TO KEEP THE COTTON DISSOLVED SOLUTION FR 10 -15 DAYS....TO GET A THICKER SOLUTION?

  • @michelleross9782
    @michelleross9782 4 роки тому +4

    New Subscriber who is enjoying your content. I had a question. Would the "thread" have been better if you had used a larger beaker with more sulfuric acid to shoot the copper solution into? I was just thinking if there was more volume to reduce clumping it might have been better result? Thank you for your time & expertise to share such amazing scientific wonders with everyone....

  • @madisonlg3033
    @madisonlg3033 9 років тому +11

    Thank you very much for this demonstration, very impressive. I wanted to perform a chemical demonstration for a school chemistry class, however the dissolution of the cotton wool did not succeed. Is there a specific duration required for the solution to thicken? We used copper sulphate, as well as sodium hydroxide, however the product was too thin and did not produce the reaction sought after. Please any advice is appreciated! Thank you!

    I'm a student attempting to conduct this experiment. I have a mediocre knowledge of high school chemistry and just want to ask the following questions:
    1.) If an aqueous solution is a mixture of in part water and a given substance, can we just dilute 100% ammonia to a 25% concentration by simply adding water (H2O)?
    2.) what does the 'n' in the (H2O)n mean in the given chemical formula of the resulting product?
    All input are appreciated!

    • @Archiekunst
      @Archiekunst 8 років тому +7

      +john binay I don't think you can get 100% ammonia. That's liquid ammonia. But whatever high percentage ammonium hydroxide solution you have, you can dilute it. Be careful of ammonia fumes.
      The chemical formula of the complex Cu(NH3)4(H2O)n represents a structure. Imagine a 3D octahedron (two pyramids attached at the base). The Cu+ ion will sit at the centre of this octahedron. The 4 NH3 molecules will be at the 4 horizontal vertices and the remaining 2 vertical vertices will be occupied by H2O. So n=2 in this case. Look at pictures of 'tetraamine copper coordination complex'. Remember that an octahedron has 8 faces and 6 vertices.
      This is irrelevant to the stoichiometry. Water is always in excess so you don't have to worry about where the molecules come from.

      Generally 25% is available in market. Stay safe it causes irritation in eyes and very strong smell. Did the same experiment in my project related to fabric chemistry, and I won the contest.

    • @kiranbodipati6870
      @kiranbodipati6870 6 років тому

      David Longman
      The formula of the compound formed in the end should be [Cu(NH3)4](OH)2
      So you can use either a normal copper compound with NaOH anD NH4OH or only by taking a copper hydroxide compound with nh4oh
