Yeast Hydrogen Peroxide Lab

Yeast and hydrogen peroxide experiment

There were students in the past who wanted to study the change between yeast and hydrogen peroxide, so they set up a test.

Put yeast in a container and pour hydrogen peroxide into it. Russia, see the effervescent surge, like a spring.

The reason is that yeast contains enzymes, which can promote the decomposition of hydrogen peroxide. For hydrogen peroxide, when encountering the enzyme of yeast, it is accelerated into water and oxygen, which is a bubble.

Students carefully observe the number and speed of bubbles, and record them in the book. Change the amount of yeast and the concentration of hydrogen peroxide, and test again.

If the amount of yeast increases, the reaction speed will cause the bubbles to develop disease; if the hydrogen peroxide concentration rises, the reaction will also be dramatic, and the bubbles will become more and more complex.

From this perspective, yeast has a great effect on the decomposition of hydrogen peroxide. Students have reached this conclusion, and their understanding of chemistry has deepened.
