What has the author Kirk L Shanahan written?
Kirk L. Shanahan has written: 'The effect of Fe+, Cr+, Ni, and Mn+ ions on decomposition of hydrogen peroxide solution' -- subject(s): Ions, Decomposition (Chemistry), Hydrogen peroxide
What is the enzymatic effects of materials on hydrogen peroxide?
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.
Another name for hydrogen peroxide?
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
What effect does hydrogen peroxide have on potato and does it differ for each type of potato?
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.
In a hydrogen peroxide and yeast experiment what is the purpose of the cups with yeast and nothing?
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.
Does hydrogen peroxide sting on cuts?
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.
What effect does catalase have on the breakdown of hydrogen peroxide?
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.
Why do you not feel warmth when hydrogen peroxide is used on your skin?
It has a cooling effect while it works and bubbles.
What does hydrogen peroxide do in a glow stick?
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.
How does temperature effect hydrogen peroxide?
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.
Why does yeast froth when put in peroxide?
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.
How do set up an experiment to measure the effect of temperature on catalase?
Create a control group by placing a measured amount of catalase solution in a test tube. Prepare test tubes with catalase solution at varying temperatures (e.g., using water baths at different temperatures). Add a known amount of hydrogen peroxide to each test tube and measure the rate of oxygen gas production as the catalase breaks down the hydrogen peroxide. Record and compare the rate of reaction at different temperatures to determine the effect of temperature on catalase activity.
