What happens when manganese dioxide is added to hydrogen peroxide and why was manganese dioxide added to the test tube containing hydrogen peroxide?
When manganese dioxide is added to hydrogen peroxide, it acts as a catalyst, increasing the rate of the decomposition of hydrogen peroxide into water and oxygen gas. Manganese dioxide was added to the test tube containing hydrogen peroxide to catalyze the reaction and speed up the decomposition process.
What happens when crushed potato was added to hydrogen peroxide?
When crushed potato is added to hydrogen peroxide, the enzyme catalase in the potato catalyzes the decomposition of hydrogen peroxide into water and oxygen gas. This reaction produces bubbling or foaming as the oxygen gas is released.
Why is ammonia water is added to hydrogen peroxide?
Ammonia water is added to hydrogen peroxide to stabilize the hydrogen peroxide solution, preventing it from decomposing rapidly. This helps to extend the shelf life of the hydrogen peroxide solution and maintain its potency for longer periods of time.
What happens when hydrogen peroxide is added to baking soda?
When hydrogen peroxide is added to baking soda, it undergoes a chemical reaction that produces water and oxygen gas. This reaction is exothermic, meaning it releases heat energy. The oxygen gas bubbles that are produced can help to clean and remove stains.
What happens when you mix hydrogen peroxide and iodine and sugar?
Hydrogen peroxide is a toxic substance that is sometimes made in our cells due to some chemical reactions. It is poisonous so cells produce an enzyme called 'Catalase' which break down hydrogen peroxide to water and oxygen. Because catalase is in our blood, if hydrogen peroxide is added to it, it breaks down: Blood + H2 O2(hydrogen peroxide) --changes to-- H2O (water) + O2 (oxygen).
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).
Why platinum is added to the storage container and not to the hydrogen peroxide?
Platinum is added to the storage container instead of the hydrogen peroxide because platinum acts as a catalyst in the decomposition of hydrogen peroxide, speeding up the reaction without being consumed in the process. This allows for better control of the reaction rate and helps to ensure that the hydrogen peroxide is not prematurely activated before use.
What would you expect to see if platinum were added to hydrogen peroxide solution?
If platinum were added to hydrogen peroxide solution, you would likely observe bubbles of oxygen gas being produced. Platinum can act as a catalyst to help decompose hydrogen peroxide into water and oxygen.
Why is the permanganate added slowly to the hydrogen peroxide solution?
To avoid a violent reaction.
Why does boiled liver react with Hydrogen Peroxide?
Boiled liver reacts with hydrogen peroxide because liver contains enzymes called catalase, which catalyze the breakdown of hydrogen peroxide into oxygen gas and water. This reaction produces bubbles of oxygen gas, which is visible as a foamy reaction when hydrogen peroxide is added to boiled liver.
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.
How can one effectively test hydrogen peroxide?
To effectively test hydrogen peroxide, you can use a chemical indicator like potassium iodide or potassium permanganate. When hydrogen peroxide is added to these indicators, it will cause a color change, indicating the presence of the compound. Additionally, you can also use a gas sensor to detect the release of oxygen gas when hydrogen peroxide decomposes.
