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.
Materials can act as catalysts to break down hydrogen peroxide into water and oxygen. Enzymes like catalase and peroxidase found in living organisms facilitate this reaction, speeding up the decomposition of hydrogen peroxide. This enzymatic effect helps protect cells from damage caused by hydrogen peroxide accumulation.
Catalase, an enzyme found in many living organisms, accelerates the breakdown of hydrogen peroxide into water and oxygen. It does this by lowering the activation energy required for the reaction, making the process faster. This decomposition of hydrogen peroxide into water and oxygen helps protect cells from damage caused by this reactive molecule.
Hydrogen peroxide in a glow stick acts as an oxidizing agent. When mixed with a dye and a fluorescent compound, it triggers a chemical reaction that produces light. The peroxide reacts with the other chemicals in the presence of a catalyst to create the glowing effect.
Temperature can impact the rate of a hydrogen peroxide reaction. Generally, increasing the temperature can increase the rate of the reaction as it provides more energy for molecules to collide and react. However, extremely high temperatures can also lead to the decomposition of hydrogen peroxide.
Hydrogen peroxide is toxic to cells and can cause harm when present in high concentrations in the body. In small amounts, it is naturally produced in our cells and plays a role in immune response. However, excessive exposure to hydrogen peroxide can lead to cellular damage and oxidative stress, contributing to various health issues.
water and oxygen will be produced!!

Hydrogen peroxide can cause an oxidative reaction on potatoes, which can change their texture, taste, and color. The effect may vary slightly depending on the type of potato due to differences in starch content and enzyme composition, but in general, most potatoes will exhibit a similar reaction to hydrogen peroxide.
The cups with yeast and nothing serve as a control in the experiment to compare the rate of reaction when hydrogen peroxide is added. By observing how the control cup behaves without the hydrogen peroxide, we can compare any changes in the cups with yeast and hydrogen peroxide to see the effect of the reaction.
Yes it will sting first you don't feel anything then it makes bubbles and that's when the stinging comes. It does not effect most people, some are more sensitive than others when peroxide is applied.

It has a cooling effect while it works and bubbles.

Yeast produces an enzyme called catalase, which breaks down hydrogen peroxide into water and oxygen gas. When yeast is added to hydrogen peroxide, the catalase enzyme reacts with the peroxide, generating oxygen gas bubbles, which causes the frothing effect.
When a potato is exposed to hydrogen peroxide, a reaction occurs due to the enzyme catalase present in the potato cells. This enzyme breaks down hydrogen peroxide into water and oxygen, leading to the formation of bubbles. This observation demonstrates the catalytic activity of enzymes and highlights the potato's ability to metabolize hydrogen peroxide, which is a toxic byproduct of cellular processes. The bubbling effect is a clear visual indication of this enzymatic reaction.
The IUPAC name is hydrogen peroxide. Other, less common, names include dioxidane and dihydrogen dioxide If you let it sit out in open air, it will decompose into H2O and O2. 2H2O2 --> 2H2O + O2
