Saturday May 11th, 2013 01:44 Chemistry experiment – KMnO4 + NaOH + sugar

Potassium permanganate solution changes colour when poured into sodium hydroxide and sugar solution. Colours are as follows: – purple (MnO4- ions) – blue (MnO4 3- ions) – green (MnO4 2- ions) – orange (Mn 3+ ions)

      There’s something better you can do with KMnO4. Shovel a little into a test tube, then add a couple ml H2SO4. Shake gently a few minutes till you see a dark pretty green liquid. Then drop a popsicle stick or wood twig into it. Be sure you are filming so you can post it here.

      can you tell me which is which?!?!

    • xueyuki May 24, 2010 at 4:49 pm

      hello! may i know the proportions of your reagents? what was your concentration of NaOh and KMnO4 in the first place?^^ thank you!

    • pyropakman June 26, 2010 at 4:55 am

      @FractAlkemist :Yeah….don’t do that. You make the dangerous anhydride, Manganese Heptoxide, Mn2O7. Any organics in the vicinity will combust vigorously and dangerously.

      Any dirt, any dust, any residue on the inside of a flask: it counts.

      I have a question for a chemist: How do I remove oil/petrolium from water? I want to distill the contaminated water, but since oil has a lower boiling point than water, it will rise up with the steam and end up in the containment jug along with the “pure” water. Should I pre-treat the water with sodium Hydroxide to break down the petrolium, and then distill it?

      @MrsBazzingaa I don’t think they purple stuff is the sugar.

    • yongrenjie August 6, 2010 at 6:15 pm

      @MrsBazzingaa Well the extremely cool purple liquid in the beaker is potassium permanganate. The solid is sugar, it can’t be sodium hydroxide because NaOH is extremely hygroscopic. The other one is sodium hydroxide.

      There is no orange, because Mn 3+ nearly doesn’t exist. There are pale pink Mn 2+.

      1stly You added sugar, then NaOH and then KMnO4 ?? Is that right??

    • duniastaa March 14, 2011 at 1:53 am

      Ok, i did it myself on my chemistry lesson. It does work, but You need to get the right balance of those ingredients. We did it exactly like on this vid but we needed to put some water into K2MnO4 bcoz firstly it was too dark… Sorry for my english mistakes, i am from Poland ^ ^

    • JRV95 March 17, 2011 at 9:10 am

      @Taytay1413

      KMnO4 (Potassium Permanganate) + NaOH ( Sodium Hydroxide) + C6H12O6 (Glucose) ->

      Not sure about the products, so that means it probably isn’t balanced but those are the reactants. I would work it out and put the states of the products and reactants but I’m lazy and I want some cheese sticks.

    • RsGhost1 March 27, 2011 at 5:13 am

      Wow :O I assume the NaOH is used to slow the dissolving proces of MnO4?

    • commercialmats May 17, 2011 at 4:23 am

      That is pretty cool. I think it is interesting how it will change between more then 2 colors like that.

Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you?
