Catalyst and Inhibitors home experiments My teacher assigned me a science experience involving catalysts and inhibitors at home.
I think I understand the principle of it, but I fail to find possible experiments that I can do at home with a thermostat and some home substances.
The experience:
3 reactions...
1 with the catalyst,
1 with the inhibitor,
1 without anything.
I will compare them by measuring the reaction speed with a factor (preferably the heat variation).
EDIT: I can also measure the volume of the product.
Thank you.
You might look up the decomposition of hydrogen peroxide, $\ce{H2O2}$. The 3% solution sold as antiseptic should be safe to use at home, as would be some readily available catalysts and inhibitors.
Horseradish might be used for a catalyst... but don't eat it in the lab.
To measure speed of reaction, measure gas evolution with an inverted, liquid-filled graduated cylinder or small measuring cup over time.
You can have fun burning things (carefully) in the evolved $\ce{O2}$, too.
