There was a lot of foam because of the enzyme catalse that is in the potato.

What effect does hydrogen peroxide have on potato and does it differ for each type of potato?
The hydrogen peroxide foams.
What happen when a raw potato is mixed with hydrogen peroxide?
The enzyme is catalase. It can exist without adding hydrogen peroxide. The hydrogen peroxide simply activates the enzyme.
Why does bubbling occur when hydrogen peroxide is added to the catalase potato?
The hydrogen peroxide, H2O2 , is being decomposed into water and oxygen gas (the bubbles).
How do you reduce hydrogen peroxide to water in homely method?
You can decompose hydrogen peroxide into water by adding a few pieces of uncooked diced potato or liver to it. Both potatoes and liver contain enzymes that will break down hydrogen peroxide.
What were the differences between the reactions of fresh liver and potato cubes in hydrogen peroxide?
Because liver has more catalase than potatoes.

How does a crush potato differ from a whole potato when hydrogen peroxide is added to each separately?
it tasts funny =)

If you add a piece of hydrogen peroxide tiny gas bubbles will form. However if you crush the piece of potato first more gas bubbles will form. Explain these observations?
The crushed piece has a greater surface area, and so the reaction takes place easier and faster.

Why do the boiled and unboiled potato extracts differ in their action on hydrogen peroxide?
hope this is correct. it is because the boiled potato has a denatured enzyme resulting it not to have a reaction with h2o2 while the unboiled potato has no denatured enzyme that's why it reacts.
Do potatoes have catalase?
Yes they do. Catalase in general seems to protect organisms, including potato cells, from the effects of hydrogen peroxide. In plants, catalase is primarily located in peroxisomes, cell organelles which are like lysosomes, but break down simpler molecules. Catalase is involved in decomposition of hydrogen peroxide generated during cellular processes such as photorespiration and oxidation of fatty acids. Hope this helps :)
What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice?
Question: What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice? In this investigation, the prediction that if the acidity of potato juice is decreased then the volume of foam was increased was proven incorrect. Catalase is damaged by acid. The lowest foam volume was 24 ml with the highest acidity, pH6, However the highest foam volume was an average of 42 ml with the second lowest acidity level,pH8 The third highest volume was 35 ml with the second highest acidity level pH7, and the second lowest foam volume was 30 ml with the lowest acidity level pH9.
How does Hydrogen peroxide decomposes much faster in the presence of enzyme catalysts?
Try a peroxidase enzyme. For example "Versatile peroxidase", Jena Biosciences #EN-203L is an extremely effective catalyst.
What happens when you heat hydrogen peroxide?
I presume you want to heat the catalyst to activate it, but here is an experiment you can do at room temperature to answer your question about a catalyst and hydrogen peroxide. The amount of catalyst available to react is increased by dissolving it in water instead of by heating. CAUTION: Perform this away from combustible materials and ignition sources (flame or spark)! 1. Cut a small potato (peeled or not) into little wedges. 2. Put the pieces in a blender with an equal volume of water. 3. Blend until liquified to a thin soupy consistency. 4. Pour into a medium or large measuring cup or glass bowl. 5. Add a splash of hydrogen peroxide. Watch it produce a starchy foam containing oxygen! You should gets lots of foam from a little hydrogen peroxide. Try adding more if the reaction stops quickly. The potato contains a catalyst called catalase. It helps release oxygen from hydrogen peroxide, turning it quickly into water and oxygen. The bubbles last a long time because of (I think) the starch in the foam. The best thing about this experiment is that it lets you "see" how much oxygen you make. Oxygen is colorless and odorless and would otherwise mix invisibly into the air. Pure oxygen speeds up combustion reactions greatly. Be careful how you dispose of it.
