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.
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.

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.
Hydrogen peroxide exposure may also result in hypersensitive response, which is the death of a small number of host cells at the site of infection, for the purpose of limiting pathogenic infection. [ 30 ] [ 31 ] ROS production in plants can be used as a readout for successful pathogen recognition via a luminol - peroxidase based assay.

Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide.
