Because your blood contains an enzyme called peroxidase that explicitly exists for the purpose of catalyzing the decomposition of peroxides.
No. Hydrogen peroxide is usually dissolved in water to make it more stable. The peroxide you buy at the pharmacy is 3% hydrogen peroxide and 97% water. Pure hydrogen peroxide, which is a dangerously strong oxidizer, can explosively decompose into water and oxygen.
When sodium peroxide is dissolved in water, it reacts to produce sodium hydroxide and hydrogen peroxide. This reaction releases oxygen gas as a byproduct, which can be observed as bubbles. The solution becomes alkaline due to the formation of sodium hydroxide.
Hydrogen peroxide and yeast can react to produce oxygen gas and water. The yeast acts as a catalyst, breaking down the hydrogen peroxide into oxygen and water.
Mixing iron nitrate and hydrogen peroxide produces oxygen gas. The reaction between iron nitrate and hydrogen peroxide results in the decomposition of hydrogen peroxide to produce oxygen gas as one of the products of the reaction.
Yeast and hydrogen peroxide produce oxygen gas as a byproduct of their reaction. The yeast acts as a catalyst to break down the hydrogen peroxide into water and oxygen.
When a raw potato is mixed with hydrogen peroxide, the enzyme catalase in the potato helps break down the hydrogen peroxide into water and oxygen gas. This reaction produces bubbles of oxygen gas as a result of the decomposition of hydrogen peroxide.
The bubbles could be viewed as a sign that the peroxide is "eating" the bacteria. You will notice after a while that fewer and fewer bubbles appear, that is because the bacteria is getting killed.
No. Hydrogen peroxide is usually dissolved in water to make it more stable. The peroxide you buy at the pharmacy is 3% hydrogen peroxide and 97% water. Pure hydrogen peroxide, which is a dangerously strong oxidizer, can explosively decompose into water and oxygen.

Streptomyces bacteria are typically catalase positive, meaning they produce the enzyme catalase which breaks down hydrogen peroxide into water and oxygen. This results in the formation of bubbles or effervescence when hydrogen peroxide is added to a culture of Streptomyces.
Skittles dissolve in hydrogen peroxide primarily due to the sugar and color additives they contain. Hydrogen peroxide acts as a strong oxidizing agent, breaking down the sugars and causing the colors to leach out. The reaction can produce bubbles of oxygen gas as the hydrogen peroxide decomposes, which contributes to the visible dissolution process. This interaction highlights the chemical nature of both the candy and the oxidizing agent.
Chryseobacterium species are catalase-positive, meaning they produce the enzyme catalase, which helps break down hydrogen peroxide into water and oxygen. This enzyme leads to the formation of bubbles when hydrogen peroxide is added to a bacterial culture.
When sodium peroxide is dissolved in water, it reacts to produce sodium hydroxide and hydrogen peroxide. This reaction releases oxygen gas as a byproduct, which can be observed as bubbles. The solution becomes alkaline due to the formation of sodium hydroxide.
Bubbles can be caused by chemical reactions that produce a gas as a byproduct. For example, when vinegar (acetic acid) reacts with baking soda (sodium bicarbonate), it produces carbon dioxide gas, which forms bubbles. Other reactions that produce gas, such as fermentation in yeast or the decomposition of hydrogen peroxide, can also create bubbles.
Peroxisomes are the enzyme-filled sacs found in the liver that produce hydrogen peroxide as a byproduct of their metabolic functions. Hydrogen peroxide is then broken down by the peroxisome's enzymes to prevent cellular damage.
When liver and hydrogen peroxide mix, they produce a liquid called hydrogen peroxide. The liver contains an enzyme called catalase, which breaks down hydrogen peroxide into water and oxygen gas.
Hydrogen peroxide and yeast can react to produce oxygen gas and water. The yeast acts as a catalyst, breaking down the hydrogen peroxide into oxygen and water.
