What is produced when hydrogen peroxide and yeast are mixed?

Answer 1

Yeast does not react with hydrogen peroxide but it is a catalyst.

Hydrogen peroxide (H202) decomposes into H2O and O2. This is always happening but at a very low rate so you don't notice it. If you add yeast to hydrogen peroxide it will speed up the decomposition of H2O2. However the yeast does not react with the H2O2 and nothing is chemically altered in the yeast. That is because yeast is a catalyst.

Answer 2

Author's note, updated February 2008: The question I get asked most by readers is, "Can I mix the hydrogen peroxide and vinegar into one sprayer?" The short answer is: EEK - No! The longer answer is: never mix hydrogen peroxide and vinegar together in one container. The resulting chemical, peracetic acid, can harm you when mixed together this way if you accidentally create a strong concentration in this fashion. Peracetic acid also has entirely different characteristics and properties than either hydrogen peroxide or vinegar. Additionally, we don't know if peracetic acid kills the same group of pathogenic food-borne bacteria when used this way as a spray - it very well may not.

I have long used a 50/50 mix of vinegar/hydrogen peroxide, stored in plastic bottles, as a bore cleaner for my handguns that use plain cast lead bullets. The mixture dissolves lead - a lead bullet placed in a glass ashtray filled with the fluid will be reduced to powder! I plug the breech end of the barrel, stand it vertically, and fill with the mix. When the fizzing and foaming stops, I pour it out and run a patch through a completely clean barrel.

Answer 3

nothing. yeast need sugar or they won't do anything. Additionally hydrogen peroxide is toxic, which is why the body goes to such extent to break it down. Even if there was sugar the yeast would die.

....You may find it bubbles ever so slightly as the hydrogen peroxide breaks down into water and hydrogen, but that would happen anyway.

Answer 4

During the reaction, the yeast's enzyme "catalase" turns hydrogen peroxide into water and oxygen, both harmless to it. So when you pour hydrogen peroxide on the yeast, you are seeing the effect of
this enzyme and the chemical reaction it mediates. When yeast metabolizes sugar, they produce carbon dioxide as a by product of metabolism. So the production of carbon dioxide will not be immediate, but as they begin to use the sugar, bubbles will appear. These bubbles will be carbon dioxide. They also produce ethanol (alcohol) in the balanced chemical reaction.

So: water, oxygen, carbon dioxide, and ethanol.

You get something called elephants toothpaste...... go to sciencebob.com

Answer 6

It makes NaCl (Sodium Chloride) + H2O (Water). Otherwise known as Salt Water. It also foams during the reaction.

Answer 7

bubbles
