The strength of a solution may be described as a percentage or volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen during decomposition.Thus, a 3% solution is equivalent to 10 volume and a 6% solution to 20 volume, etc. Answer taken from Wikipedia 19/01/2009
Depending on the concentration of the hydrogen peroxide, (if low enough) it will just decompose into water and oxygen gas. If the hydrogen peroxide is high enough in concentration it will just heat up and mix with the water (most likely the first will occur).
Hydrogen peroxide decomposes through a thermodynamically favourable reaction: 2H2O2 → 2H2O + O2 The rate of this reaction increases with temperature and depends on factors like its concentration, pH and the prescence of a catalyst. Thus, a bottle of hydrogen peroxide can decompose when stored under unfavourable conditions.
yes
It means that the concentration of the peroxide is such that for every 1mL of hydrogen peroxide solution, 100mL of oxygen will be produced if fully reduced, catalyzed, exposed to light, heated or decomposed in any manner to the fullest extent. The fullest extent means the end point where every molecule of hydrogen peroxide releases one oxygen atom, and is converted into water.
Hydrogen Peroxide (H2O2) is a strong oxidizer. As such it's pretty lethal to most bacteria if it comes in contact with them. Note that it's also pretty deadly to most cells it comes in contact with and, depending on the concentration, can be dangerous to be around. The stuff you get in a pharmacy is about 3% concentration, and is not harmful.
3%
Generally, hydrogen peroxide bottles contain 1 to 3% peroxide.
Depending on the concentration of the hydrogen peroxide, (if low enough) it will just decompose into water and oxygen gas. If the hydrogen peroxide is high enough in concentration it will just heat up and mix with the water (most likely the first will occur).
it doesnt
Oxidative stress was induced by adding hydrogen peroxide at 0.25 mM for 2, blotting in the three cell lines after hydrogen peroxide stimulation.
One possibility is mentioned in the link.
One can remove seborrheic keratoses by the use of hydrogen peroxide and duct tape. Dilute the hydrogen peroxide to 25% concentration and apply to the affected areas of the skin with a cotton cloth. Cover the area with duct tape quickly to ensure the hydrogen peroxide does not evaporate.
No. Hydrogen peroxide is not flammable, especially since the commercial concentration of 3% is 97% water. In high concentrations above about 50% hydrogen peroxide is a dangerous oxidizer that, while not flammable itself, can set other materials on fire.
Hydrogen peroxide is a teeth whitener, google "hydrogen peroxide teeth."
Hydrogen is an element.Hydrogen peroxide is a compound.
hydrogen+peroxide
Hydrogen peroxide decomposes through a thermodynamically favourable reaction: 2H2O2 → 2H2O + O2 The rate of this reaction increases with temperature and depends on factors like its concentration, pH and the prescence of a catalyst. Thus, a bottle of hydrogen peroxide can decompose when stored under unfavourable conditions.
