Sodium Iodide, Ultra Pure, 100 Grams

This is a good compound for preliminary testing for oxidation of other chemical compounds. A sodium iodide solution if absorbed into paper that contains starch and dried and then exposed to an oxidation chemical: free iodine will be liberated which will react with the starch in the paper and produce a blue color, thus indicating an oxidation reaction. Hydrogen peroxide and chlorine gas will produce such a reaction with starch paper impregnated with NaI.

Works perfect!! Just wish there was bigger quantities that could be purchased at a time for a discounted price.

My son wanted to order this for a explosive science type experiment. We could never get the ratio correct, but it did work just...not as expected. It is pretty expensive for a small bottle so it was a little hard to try it a few times without having to buy a few bottles which got very expensive for us.

Worked great for the elephant toothpaste volcano 🌋 daughter didn’t get the A but great for dual purpose project

Far nicer and more effective than I hoped for

To make really good elephant toothpaste with Sodium Iodide and Hydrogen Peroxide, you need 30% Hydrogen Peroxide (not the 3% cheapo stuff for cuts). This requires protective gear, as it reacts very fast and produces tremendous heat (enough to produce "steam" coming off the foam). It is too hot for yeast toothpaste, as the heat kills the yeast.
