What is hydrogen peroxide and what is it used for???????

Answer 1

its used to bleach hair

Answer 2

Hydrogen peroxide (H2O2) is one of the most powerful oxidizers known. Through catalysis, H2O2 can be converted into hydroxyl radicals (.OH). When exposed to other compounds hydrogen peroxide dismutates readily.
Hydrogen peroxide is odorless and colorless, but not tasteless.

It is NOT bleach, as the latter is a mix of hypo-chlorite salts and contains ClO- ions.

Despite its power, H2O2 is a natural metabolite of many organisms, which decompose the H2O2 they produce into oxygen and water. H2O2 is also formed by the action of sunlight on water - a natural purification system for our environment.

We need hydrogen peroxide for a multitude of other chemical reactions that take place throughout the body. For example, we now know that vitamin C helps fight infections by producing hydrogen peroxide, which in turn stimulates the production of prostaglandins. Also lactobacillus found in the colon and vagina produce hydrogen peroxide. This destroys harmful bacteria and viruses, preventing colon disease, vaginitis, bladder infections and a host of other common ailments.

In our the lab, H2O2 is widely used as a positive control for DNA damage in cultured cells, as the OH- radicals are very unstable and react with the macromolecules, especially genomic DNA, causing double strand breaks. The presence of breaks in the DNA molecule, activate what are called "cell cycle checkpoints" which induces healthy cells to stop growing and dividing until the damage is repaired.

Answer 3

Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant, as an oxidizer, and in rocketry (particularly in high concentrations as high-test peroxide (HTP) as a monopropellant), and in bipropellant systems. It's is used for cuts and scrapes to keep them clean, Diluted H2O2 (around 5%) is used to bleach human hair, hence the phrases peroxide blonde and bottle blonde. It can absorb into skin upon contact and create a local skin capillary embolism which appears as a temporary whitening of the skin. It whitens skeletons that are to be put on display. 3% H2O2 is used medically for cleaning wounds, removing dead tissue, or as an oral debriding agent. Most over-the-counter peroxide solutions are not, however, suitable for ingestion.

The Food and Drug Administration (FDA) has classified hydrogen peroxide as a Low Regulatory Priority (LRP) drug for use in controlling fungus on fish and fish eggs

Answer 5

It is commonly used a a bleach, in particular for the hair, head or facial. However it is a superb tooth whitener. To use as such obtain a mouth shield as used by sportsmen and mould it to your teeth, mix 2 parts hydrogen peroxide with 2 parts baking soda, . Line the mould with the paste and leave for 15/20 minutes then rinse out. DO NOT SWALLOW. This is similar to the treatment you will pay a dentist £100s for.

it is used for coloring the hair.

Answer 7

Water is H2O. Hydrogen peroxide is H2O2, and it can be used as a bleaching agent or a rocket fuel, so it is dangerous stuff when pure.

Answer 8

H2O2. The formula is the same as water only it has an extra oxygen atom. It is unstable and gives up the extra oxygen easily. Since oxygen is a very active substance and combines readily with organic substances, it makes a good bleach and it is a good disinfectant.

Answer 9

Among the many other things listed above it is also something doctors prescribe following a tonsillectomy. You have to gargle with it three times a day to keep the wounds clean. And it tastes disgusting!

Answer 10

H2O2 can be used for many things. It is a disinfectant, can be used for rocket fuel and is sometimes used in mouthwash or in drugs. It is highly reactive and can be dangerous if mixed with certain chemicals (like the liquid bombs in that conspiracy in England).

Answer 11

The usual uses for this chemical are for the colouring of hair. It is also used in wound management by surgeons, as it promotes healing.
