    i'm wondering about 2:59 a point of reaction on chemical formula. like 6. IO2 on the point

    Nice video :) I Have a question about the colors: Isnt it the reaction I- + I2 --> I3- that produces the yellow color?

    • @drsjamesserra
      @drsjamesserra 4 ปีที่แล้ว +3

      I was thinking the sam thing. I2 with starch turns blue, the I3- is yellow.

      @drsjamesserra 4 ปีที่แล้ว +2

      Turns out I3- or |5- forms a complex with starch causing this colour:www.chemistryviews.org/details/education/10128441/Why_Does_Iodine_Turn_Starch_Blue.html

    Hi, thank you for the video. I want to perform this reaction as a demonstration for my kids. I saw that in some procedures vitex starch was added to solution 2 (malonic acid, MnSO4). Is it required (since starch is the indicator for iodine), and is it crucial to use vitex starch or can standard starch be used (is it a solubility issue?). Thanks.

    If you were to seal this off, wouldn't this theoretically run forever?

    • @voltcorp
      @voltcorp 8 ปีที่แล้ว +36

      no because at each cycle the active ingredients get "used up" as the amount of the final compound increases.

    Isn't this in the same family as the Belousov-Zhabotinsky reaction?

    • @bencebiro6421
      @bencebiro6421 2 ปีที่แล้ว

      Yes, basically they are the same. The only difference is that in Belusov Zhabktinsky reaction bromine is involved instead of iodine.

    hello thank you for the video. I performed this in our school club. But i don't know why these reactions happen. I tried to find information on internet, but i couldn't get any useful information. could you explain?? anyone okay.. help me+pleas understand my poor english.. thank you

    what is the reason for the vortex in the liquid?

    • @missp2513
      @missp2513 7 ปีที่แล้ว +5

      It is caused by a stir bar which is stirring the solution to keep it mixing.

    1-Please hold the pin properly !!
    2-change this cheep nails color!!
    3-I don't know why does MIT changes from full courses Videos to the clips from lectures??
    4- thanks for this illusive type of reactions, If I saw this before when I was in the high school, I would probably specialized in Chemistry !!!!

    Why does this courseware have a jazzy intro theme riffed off a track in the 1986 Commodore 64 game, Ark Pandora?

    It's pen, and she writes more legibly than I do so whatever works. There is no correct way to hold a writing implement AFAIK
    The nail color has, thus far, been rotating colors through each video and coordinated with the content of the video in some manner. since I'm a dumb male, I cannot attest to the cheapness of the polish.
    They probably look at the viewing metrics for their long videos and see a sharp drop off at the 4 minute mark because everyone on youtube has AD
    oh look a squirrel
