What are Bleach and Chlorine?
Household bleach is a chlorine-containing chemical compound with the formula ClO. It is an aqueous solution of sodium hypochlorite, NaClO, and is used as a disinfectant, bleaching agent, and water purifier.
The product is sold in concentrated form, and when diluted with water, the chemical reaction between NaOCl ( Sodium Hypochlorite) and NaOH ( Sodium hydroxide) releases chlorine gas. This gas is also used for bleaching and disinfection. (source)
The standard household bleach sold today is usually 3–6% sodium hypochlorite and may be hypochlorite (when dissolved in water) or the anhydrous form (dried, powdered bleach sold for consumer use) the concentration of about 5–7%.
Household bleach may be used to disinfect cutting boards, countertops, vegetables, fruits, clean bathrooms, toilets, and other surfaces.
However, in some countries, the product is not recommended for disinfecting children’s toys or baby bottles.
In swimming pools, the concentration of chlorine in water is adjusted to 2–10 parts per million (ppm) for effective disinfection.
A variety of uses are commonly recorded for household bleach, including general cleaning, disinfecting, odor removal, bleaching of fabrics and hair, preparation of natural extracts used in the manufacture of perfumes, and in copy machines to remove streaks in photographs.
General household bleach may be used for cleaning, but this is likely to leave undesirable white marks on some fabrics, especially absorbent ones.
