Sodium hypochlorite (commonly known in a dilute solution as bleach) is a chemical compound with the formula NaOCl or NaClO, comprising a sodium cation ( Na+. ) and a hypochlorite anion ( OCl−. or ClO−. ). It may also be viewed as the sodium salt of hypochlorous acid.

Anhydrous sodium hypochlorite can be prepared but, like many hypochlorites, it is highly unstable and decomposes explosively on heating or friction. The decomposition is accelerated by carbon dioxide at atmospheric levels. It is a white solid with the orthorhombic crystal structure. Sodium hypochlorite can also be obtained as a crystalline pentahyd...
At typical ambient temperatures, sodium hypochlorite is more stable in dilute solutions that contain solvated Na+ and OCl− ions. The density of the solution is 1.093 g/mL at 5% concentration, and 1.21 g/mL at 14%, 20 °C. Stoichiometric solutions are fairly alkaline, with pH 11 or higher since hypochlorous acid is a weak acid: 1. OCl− + H2O ⇌ HOCl +...
In solution, under certain conditions, the hypochlorite anion may also disproportionate (autoxidize) to chloride and chlorate: 1. 3 ClO− + H+ → HClO3 + 2 Cl− In particular, this reaction occurs in sodium hypochlorite solutions at high temperatures, forming sodium chlorateand sodium chloride: 1. 3 NaOCl (aq) → 2 NaCl (aq) + NaClO3(aq) This reaction ...
Titration of hypochlorite solutions is often done by adding a measured sample to an excess amount of acidified solution of potassium iodide (KI) and then titrating the liberated iodine (I2) with a standard solution of sodium thiosulfate or phenyl arsine oxide, using starchas indicator, until the blue color disappears. According to one US patent, th...
Oxidation of starch by sodium hypochlorite, that adds carbonyl and carboxyl groups, is relevant to the production of modified starchproducts. In the presence of a phase-transfer catalyst, alcohols are oxidized to the corresponding carbonyl compound (aldehyde or ketone). Sodium hypochlorite can also oxidize organic sulfides to sulfoxides or sulfones...
Heterogeneous reactions of sodium hypochlorite and metals such as zinc proceed slowly to give the metal oxideor hydroxide: 1. NaOCl + Zn → ZnO + NaCl Homogeneous reactions with metal coordination complexes proceed somewhat faster. This has been exploited in the Jacobsen epoxidation.
If not properly stored in airtight containers, sodium hypochlorite reacts with carbon dioxide to form sodium carbonate: 1. 2 NaOCl + CO2 + H2O → Na2CO3+ 2 HOCl Sodium hypochlorite reacts with most nitrogen compounds to form volatile monochloramine, dichloramines, and nitrogen trichloride: 1. NH3 + NaOCl → NH2Cl+ NaOH 2. NH2Cl + NaOCl → NHCl2+ NaOH ...
Sodium thiosulfateis an effective chlorine neutralizer. Rinsing with a 5 mg/L solution, followed by washing with soap and water, will remove chlorine odor from the hands.
Sodium hypochlorite is an unstable compound composed of sodium and hypochlorite ions. It is stable in solution, though. It is light green and has the chemical formula NaClO (or NaOCl). It is a strong oxidizing agent. It is used to disinfect (kill bacteria) and as a bleach to remove stains from clothing.
In chemistry, hypochlorite is an anion with the chemical formula ClO −. It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). The Cl-O distance in ClO − is 1.69 Å.
A sodium hypochlorite cleanser is used to cleanse and soothe skin that is prone to infection and conditions such as eczema, atopic dermatitis, folliculitis and other skin conditions. The idea for cleansers came from bleach baths which were used to kill bacteria to prevent infections and treat infections after they occurred.
