Bleach contains NaCl (table salt), H2O, and NaClO (sodium chlorate).\nIt is the "ClO -" ion in the NaClO that causes things to be bleached and lose its colour.

Bleach is also known as sodium hypochlorite (NaClO), if I remember this correctly. Hot water can release some of the chlorine in the bleach as a gas. That's the distinct smell that bleach gives off. Cl is highly reactive and corrosive. That's the reason why we don't mix ammonia with bleach... it will release dangerous amounts of Cl gas. \n\nAnyway... that's probably why people think hot water will deactivate the bleach a bit. Since it's the Cl that will do most of the damage to microorganisms and the like while disinfecting. But the hot water isn't likely to release enough Cl to make the bleach ineffective or even to deactivate it. \n\nIf you're worried about it, it would probably be better to use warm water instead. It'll speed up the reaction enough to kill of whatever. Or you can use cold water. That's what we used in the lab DI (deionized) water at room temp. And it works just fine. \n\nAs a side note, if you really want to keep things disinfected. You can always buy 70% ethanol to wipe down all surfaces after you've cleaned it. I think it's much better than bleach as long as the surface is wipable. Just make sure you don't touch it after wiping, let it evaporate on its own.

When bleaching powder is added to the washing machine, it mixes with water and chlorine is released to bleach the clothes.  If the container is not kept air tight, moisture in the air will enter the powder and release the chlorine which will no longer be available to bleach the clothes.

they make colors usually white stand out more. if you have glow in the dark stuff it will make that stand out too

White sugar has had all nutrients bleached out of it.\nBrown sugar still retains some nutrients even after processing\nBrown is better.

Sodium hypochloride is a strong bleaching agent. Chemically, it is an oxidant: \n\n2 H2O + 2 ClO(1-) + 4 electrons -> 4 OH(1-) + 2 Cl(1-)\n\nThe chlorine in the hypochloride changes from one positive charge to one negative charge.\n\nWhen your clothes change colour, it is because the dyes get oxidated. Dyes usually have complex systems of double-bonds in the molecule in order to absorb visible light. These double-bonds usually are reactive and can get chlorinated (in which case some of the Cl(1-) in the equation above ends up in the molecule) or subsequently hydrolized (which results in the formation of an alcohol).

Semen contains protein (a very little bit) and not much else.  It is highly unlikely that it will make anything white (other than your sheets).

Bleach is an oxidizing agent which removes the color. You can't remove it once it has taken the color out but you can dye the area. Go to a carpet store. They should be able to assist you with matching the color..with swatches or carpet pieces. Good luck.

To bleach something is to remove or lighten its color; a "bleach" is a chemical that can produce these effects, often via oxidization. Common chemical bleaches include sodium hypochlorite, or "chlorine bleach," and "oxygen bleach," which contains hydrogen peroxide or a peroxide-releasing compound such as sodium perborate or sodium percarbonate. "Bleaching powder" is calcium hypochlorite. Bleaching may be a preliminary step in the process of dyeing.\n\nHousehold bleach or sodium hypochlorite is used in the home for whitening clothes, removing stains, and disinfecting. This is because sodium hypochlorite yields chlorine radicals—oxidizing agents readily reacting with many substances.\n\nHair bleach contains H2O2 (hydrogen peroxide), which gives off oxygen radicals as it decomposes. Oxygen and chlorine radicals both have comparable bleaching effects.\n\nChlorine bleach is often used with laundry detergent and is also commonly used as a disinfectant by homemakers and janitors. Mixing bleach and cleaners containing ammonia, or using bleach to clean up urine can create toxic chloramine gases and an explosive called nitrogen trichloride.\n\nNot all bleaches have to be of oxidizing nature. Sodium dithionite is used as a powerful reducing agent in some bleaching formulas.\n\nChlorine dioxide is used for the bleaching of wood pulp, fats and oils, cellulose, flour, textiles, beeswax, and in a number of other industries.\n\nIn the food industry, some organic peroxides (acetone peroxide, benzoyl peroxide, etc.) and other agents (e.g. bromates) are used as flour bleaching and maturing agents.

The "white" is caused by the crystalization of water molecules when they are frozen.  Light refracts off these crystals in a full spectrum (so you get white.)  When the molecules free again after getting warm, the light no longer refracts off in the full spectrum removing the white color.\n\nBTW white light is made of millions of colors...

White clothes always project a sense of purity, cleanliness. It's only natural that chefs and doctors would want to wear white for the sake of their customers.

Bleach is not an acid.  It has a pH of over 12, making it a strong base.\n\nVinegar is an acid, though.

Tite Kubo (The author) stated two different reasons. One of the reasons is symbolism. The shinigami (soul reapers) cleanse souls, just as bleach cleanses fabric. The second reason is that the author is a big Nirvana fan and Nirvana has an album titled "Bleach". \nhttp://en.wikipedia.org/wiki/Nirvana_%28band%29\nhttp://answers.yahoo.com/question/index;_ylt=At1eBgxHXlbEfDp4yDruPJMjzKIX?qid=20061108165039AALWNvB

Of course it depends entirely on the conditions. Bleach will dry about as fast as seawater under the same conditions.\n\nRemember bleach is just an aqueous salt solution. Only the water actually evaporates.

I used facial hair bleach once on my arms to bleach the hair and my skin faded. Try that maybe.
