Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
Bleaching of wood pulp is the chemical processing of wood pulp to lighten its color and whiten the pulp. The primary product of wood pulp is paper, for which whiteness (similar to, but distinct from brightness) is an important characteristic. [1]
"Bleaching powder" usually refers to a formulation containing calcium hypochlorite. [citation needed] Oxidizing bleaching agents that do not contain chlorine are usually based on peroxides, such as hydrogen peroxide, sodium percarbonate, and sodium perborate. These bleaches are called "non-chlorine bleach", "oxygen bleach", or "color-safe ...
The powder is usually white and sometimes has a strong detergent-like smell that, in my personal experience, is far more pleasant than bleach. You can also find some varieties that are unscented.

The term "bleach" originates from a French word signifying "to whiten." In essence, the process of bleaching involves whitening by removing substances that impart color to the material undergoing the bleaching treatment. [26] Bleaching is the process of decolorizing the material after it has been scoured.
Ethidium bromide (or homidium bromide, [2] chloride salt homidium chloride) [3] [4] is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis.
1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
