In particular, this reaction occurs in sodium hypochlorite solutions at high temperatures, forming sodium chlorate and sodium chloride: [22] [23] 3 NaOCl(aq) → 2 NaCl(aq) + NaClO 3 (aq) This reaction is exploited in the industrial production of sodium chlorate. An alternative decomposition of hypochlorite produces oxygen instead: 2 OCl − ...
In chemistry, hypochlorite, or chloroxide is an oxyanion 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"). [1] The Cl-O distance in ClO − is 1.69 ...
Inorganic chloramines are produced by the reaction of ammonia and hypochlorous acid or chlorine. An urban legend claims that mixing household bleach (aqueous sodium hypochlorite) with ammonia-based cleaners releases chlorine gas or mustard gas; in reality, the gas produced by the reaction is a mixture of inorganic chloramines.
Sodium hypochlorite solution, 3–6%, (common household bleach) is typically diluted for safe use when disinfecting surfaces and when used to treat drinking water. [31] [32] A weak solution of 2% household bleach in warm water is typical for sanitizing smooth surfaces before the brewing of beer or wine. [citation needed]
In dilute aqueous solution, chloramine is prepared by the reaction of ammonia with sodium hypochlorite: [5] NH 3 + NaOCl → NH 2 Cl + NaOH. This reaction is also the first step of the Olin Raschig process for hydrazine synthesis. The reaction has to be carried out in a slightly alkaline medium (pH 8.5–11).
Chlorine releasing solutions, such as liquid bleach and solutions of bleaching powder, can burn the skin and cause eye damage, [2] especially when used in concentrated forms. As recognized by the NFPA, however, only solutions containing more than 40% sodium hypochlorite by weight are considered hazardous oxidizers.
The Olin Raschig process is a chemical process for the production of hydrazine.The main steps in this process, patented by German chemist Friedrich Raschig in 1906 and one of three reactions named after him, are the formation of monochloramine from ammonia and hypochlorite, and the subsequent reaction of monochloramine with ammonia towards hydrazine.

The diffusivity of the solvated electron in liquid ammonia can be determined using potential-step chronoamperometry. [6] Solvated electrons in ammonia are the anions of salts called electrides. Na + 6 NH 3 → [Na(NH 3) 6] + + e −. The reaction is reversible: evaporation of the ammonia solution produces a film of metallic sodium.
