In chemistry, to bleach something generally means to whiten it or oxidize it. A bleach is a chemical that exhibits these properties. Common chemical bleaches include Sodium hypochlorite is a chemical compound with the formula NaClO. A solution of sodium hypochlorite is frequently used as a disinfectant and as a bleaching agent; indeed, often it is simply called bleach though other chemicals are sometimes given that name as well. Sodium hypochlorite (like all hypochlorites) is a... sodium hypochlorite, or "chlorine bleach," and "oxygen bleach," which contains The chemical compound hydrogen peroxide (H2O2) is a viscous liquid that has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant and (in high concentrations) as an oxidizer or monopropellant in rockets. Hydrogen peroxide is manufactured commercially by several processes. Inorganic processes... hydrogen peroxide. "Bleaching powder" is calcium hypochlorite. Bleaching can be a preliminary step in the process of Dyeing is the process of changing the colour of a yarn or cloth by treatment with a dye. For the majority of the thousands of years in which dyeing has been used by man to decorate clothing, or fabrics for other uses, the primary source of dye has been nature... dyeing.

Chlorine bleach is commonly used as a Disinfection The destruction of pathogenic and other kinds of microorganisms by physical or chemical means Disinfectants are chemical substances used to kill viruses and microbes (germs), such as bacteria and fungi. The ideal disinfectant would offer complete sterilization, without harming other forms of life, be inexpensive, and non-corrosive. Unfortunately... disinfectant by A stereotypical housewife A homemaker is a person whose prime occupation is to care for their family and home. The term homemaker is used in preference to either housewife or househusband because it is inclusive, defines the role in terms of activities, rather than relation to another, and is independent... homemakers and A janitors bucket with mop A janitor or caretaker (term used in British English) is a person who takes care of a building, such as a school, office building, block of flats. They are usually responsible for cleaning, maintenance and security. The title is derived from the Latin word... janitors. Bleach should NEVER be mixed with cleaners containing Ammonia is a chemical compound with the formula NH3. The molecule is not flat, but has the shape of a flattened tetrahedron known as a trigonal pyramid. In solution it forms the positively charged ammonium ion NH4+, which has the shape of a regular tetrahedron. At standard temperature and pressure... ammonia; the mixture can create toxic gases and volatile explosives.

In most color negative processes, the A silver halide is one of the compounds formed between silver and one of the halogens, notably silver bromide (AgBr), silver chloride (AgCl) and silver iodide (AgI). As a group, they are often referred to as the silver halides, and are often given the pseudo-chemical notation AgX. Silver halides... silver halide crystals present in the An emulsion is a mixture of two immiscible substances. One substance (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include butter, certain types of asphalt concrete, mayonnaise and cutting fluid for metalworking.

Photographic bleach is usually Potassium ferricyanide (K3Fe(CN)6), also known as Red prussiate or Prussian Red, is a coordination compound that is stable at room temperature and pressure and forms ruby red crystals and powder. It is manufactured by passing chlorine gas through solutions of potassium ferrocyanide. Potassium ferricyanide then separates out of... potassium ferricyanide.
