Specification

The Sodium hypochlorite is an organic compound with the formula NaClO. The IUPAC name of this chemical is sodium hypochlorite. With the CAS registry number 7681-52-9, it is also named as Hypochlorous acid, sodium salt. The product's categories are Industrial/Fine Chemicals; Biocide; Hypochlorites; Hypochlorites Essential Chemicals; Oxidation; Reagent Grade; Routine Reagents; Synthetic Reagents. Besides, it is colourless liquid with strong odour, which should be stored in a cool and well-ventilated place.

Physical properties about Sodium hypochlorite are: (1)ACD/LogP: 0.71; (2)ACD/LogD (pH 5.5): 0.71; (3)ACD/LogD (pH 7.4): 0.48; (4)ACD/BCF (pH 5.5): 2.03; (5)ACD/BCF (pH 7.4): 1.19; (6)#H bond acceptors: 1; (7)#H bond donors: 1; (8)Polar Surface Area: 20.23 Å².

Preparation of Sodium hypochlorite: this is the only large scale industrial method of sodium hypochlorite production. In this process sodium hypochlorite (NaClO) and sodium chloride (NaCl) are formed when chlorine is passed into cold and dilute sodium hydroxide solution. It is prepared industrially by electrolysis with minimal separation between the anode and the cathode. The solution must be kept below 40 °C (by cooling coils) to prevent the undesired formation of sodium chlorate.
Cl₂ + 2 NaOH → NaCl + NaClO + H₂O

Uses of Sodium hypochlorite: in household form, sodium hypochlorite is used for removal of stains from laundry. It is particularly effective on cotton fiber, which stains easily but bleaches well. Sodium hypochlorite has been used for the disinfection of drinking water. In batch treatment operations, sodium hypochlorite has been used to treat more concentrated cyanide wastes, such as silver cyanide plating solutions. Sodium hypochlorite is now used in endodontics during root canal treatments.

When you are using this chemical, please be cautious about it as the following:
It contacts with acids liberates toxic gas and can cause burns. After contact with skin, wash immediately with plenty of ... (to be specified by the manufacturer). In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Besides, this chemical is irritating to eyes, respiratory system and skin. When you are using it, wear suitable gloves and eye/face protection. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible).

You can still convert the following datas into molecular structure:
