Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the skin, and silver nitrate produces noticeable black stains. Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion.
Cummins et al., 1999, 2009, and 2013 find that Alopecurus myocuroides ' s mechanism of fenoxaprop-P-ethyl resistance reduces hydrogen peroxide concentrations at the application site, while the wild type responds with an increase.
“I advise clients to pay special attention to moisture-prone areas like bathrooms and basements, and use mold-killing solutions, such as hydrogen peroxide or vinegar, to clean these areas ...
Hydrogen peroxide is an anti-fungal and anti bacterial solution that eliminates mold on a wide variety of surfaces. Just spray the undiluted solution directly onto the mold and let it sit for 10 ...
Hydrogen peroxide and silver in solution and diluted in water is a non-toxic and low cost agent. For example, to fumigate a 1000 ft 3 (~28.32 m 3 ) area, a 20% solution (200 mL of solution in 1000 mL demineralized water) would be sprayed via fogger for 30 minutes.
A major source of chemical bleaching is hydrogen peroxide (H 2 O 2) that contains a single bond, (–O–O–). When the bond breaks, it gives rise to very reactive oxygen specie, which is the active agent of the bleach. Around sixty percent of the world's hydrogen peroxide is used in chemical bleaching of textiles and wood pulp. [7]
Hydrogen peroxide is insufficiently active as a bleach at temperature below 60 °C (140 °F), which traditionally made hot washes the norm. The development of bleach activators in the 1970s and 1980s allowed for cooler washing temperatures to be effective.
