Potato experiment with hydrogen peroxide
WebThe equation of the reaction between catalase enzyme and hydrogen peroxide substrate is as follows: Hydrogen peroxide + catalase → Oxygen + Water. 2H 2 O 2 → O 2 + 2H 2 O. This breakdown will occur most efficiently in conditions most similar to those in the human body, i.e. at a temperature of approximately 37˚c, and at a pH created by the ... http://api.3m.com/potato+and+hydrogen+peroxide+experiment+write+up
Potato experiment with hydrogen peroxide
Did you know?
WebHydrogen peroxide (H2O2) is a very pale blue liquid that appears colorless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. WebAnalyzes the effect of surface area on the rate of reaction between catalase from a potato and hydrogen peroxide. Opines that by testing the same brand of potato, they will make it a fair test. Explains that they are measuring how long it takes to collect 10 cubic cm of gas.
