SODIUM HYPOCHLORITE: WIDELY USED FOR BLEACHING DISINFECTING AND OXIDIZING PARTICLES
odium hypochlorite (NaOCl) is formed when caustic soda (NaOH) and chlorine (Cl2) react. It is widely used for its bleaching, disinfecting and oxidizing properties. General : Synonyms: hypochlorous acid sodium salt, sodium hydrochlorite, sodium chloride oxide, sodium oxychloride clorox, antiformin, B-K liquid, Carrel-dakin solution, chloros, chlorox, deosan, hyclorite, Javex, klorocin, milton, neo-cleaner, neoseptal CL, parazone, purin B, surchlor Use: Liquid bleach Molecular formula: ClONa CAS No: 7681-52-9 EC No: 231-668-3 Annex I Index No: 017-011-00-1 Physical data Appearance: colourless liquid with strong odour Melting point: Boiling point: typically 40 C (decomposes) Vapour density: Vapour pressure: Specific gravity: ca. 1.21 Flash point: n/a Explosion limits: n/a Autoignition temperature: n/a Stability : Stable. Contact with acids releases poisonous gas ( chlorine ). Light sensitive. Incompatible with strong acids, amines, ammonia, ammonium salts, reducing agents, metals, aziridine, methanol, formic acid, phenylacetonitrile. Toxicology : It is corrosive, causes burns to skin and eyes. It is harmful by ingestion, inhalation and through skin contact. It is skin irritant. Degree of harm depends upon the concentration of hypochlorite. Annex I lists only the risk phrases R31 R34. ORL-MUS LD50 5800 mg kg-1 ORL-WMN TDLO 1000 mg kg-1 IVN-MAN TDLO 45 mg kg-1 Personal protection : It is to be used in well-ventilated areas only. Protect eyes. Do not mix with acids. Sodium Hypochlorite Solution Product Identification : Synonyms: Bleach; hypochlorous acid, sodium salt; soda bleach; sodium oxychloride CAS No.: 7681-52-9 Molecular Weight: 74.44 Chemical Formula: NaOCl Product Codes: 9416, P005 Composition/Information on Ingredients Ingredient CAS No Percent Hazardous ------------- ------------ ------------ --------Sodium Hypochlorite (as NaOCl) 7681-52-9 5% Yes Water 7732-18-5 95% No Hazards Identification : Emergency Overview : Warning! Harmful if swallowed or inhaled. It causes irritation to eyes and respiratory tract and causes substantial but temporary eye injury. Sodium Hypochlorite Sodium hypochlorite (NaOCl) is formed when caustic soda (NaOH) and chlorine (Cl2) react. It is widely used for its bleaching, disinfecting and oxidizing properties.
