Where do you buy pottasium iodine, not the kind that you eat
I am trying to do the elphant's toothpaste experiment, exepct i can't fint where to but potasium iodine at! Alls that i can find on the web are pills of it to protect your thyroid. Answers and Replies
The http://www.using-hydrogen-peroxide.com/elephant-toothpaste.html" [Broken] experiment works by decomposing Hydrogen Peroxide (H2O2), with the aid of a catalyst, which is mixed with some soap. When the H2O2 decomposes it produced Oxygen gas. All that Oxygen forming makes bubbles in the soap and expands to fill (and then over-flow) the container it is placed inside.
Potassium Iodide is used, amongst other things, as a photography chemical. Although I have never done this myself so as to say for certain that it will work… There are alternative catalysts you may use to decompose H2O2. Manganese Dioxide (MnO2) will also work quite well. MnO2 is a pottery
supply chemical and is also found inside dry cell batteries. http://www.nitrogenorder.org/lessons/household.shtml#retailchem Last edited by a moderator: May 3, 2017
In case you didn't notice: it is potasium iodide vs potassium iodine.
that video in the link uses a lot of KI. i tried this with 3%H2O2 and detergent and got diddlysquat with a small amount of colorless iodine tincture used (water, alcohol, KI and NH4I). try a google product search with "potassium iodide reagent" Last edited by a moderator: May 3, 2017
Any transition metal will decompose peroxide. I've used ferric chloride. I'm sure a crushed up vitamin/mineral pill would do the trick as well. Try mashing up a chewable vitamin pill into a small volume of water and add it to the peroxide.
Yeah , just do not do it with peroxide that is 30 % and above , any type of contaminent is bad for peroxide here. Suggested for: Where do you buy pottasium iodine, not the kind that you eat

Foam is produced more slowly, but you can add a fluorescent dye to this reaction to produce elephant toothpaste that will glow very brightly under a black light.
Can you buy potassium iodide?You don't need a prescription to get potassium iodide. You can get it over the counter at local pharmacies or drugstores. If it's not available near you, you can order potassium iodide online. Make sure that the FDA has approved the version that you get.
