Elephant's Toothpaste with Different Concentrations

Chemistry demonstration of hydrogen peroxide decomposition with different concentration of reagents and catalysts. Connects to reaction order, rate law, and reaction mechanism.

1.0M potassium iodide is 166gKI/1000g water: about 1 part KI to 6-7 parts water or 16.6% KI concentration
6.0M potassium iodide is 996gKI/1000g water: about 1 part KI to 1 part water or 100% KI concentration
Would have been interesting to see 3.0M KI or 50% KI concentration

Yea but what volume of KI? 😵‍💫

[@generalingwer4341]

Very nice comparison😀

I have to watch this at school lmao

[@brenewedwellness]

Nice, I'd like less science terms and more lamens terms measurements so that I can recreate the last experiment.
