Alias:Javel water(Sodium Hypochlorite),other names:natrium chlorous; bleaching water.Molecular formula:NaClO;NaClO·5H2O。
Character:natrium chlorous(no water) of white crystal powder is no instability and easy to decompound by reacting with CO2,but stability in alkalescence condition.The concentration of effective chlorine is 100-140g/L in industry using,which color is achromatism or primrose yellow. Dissolving in water easily to produce caustic soda and instability HClO.
Mading Method:alkali solution chloridize.
Solubility of natrium chlorous in water(g/100g H2O)
| T/℃ | 0 | 10 | 20 | 30 | 40 |
| Solubility | 29.4 | 36.4 | 53.4 | 100 | 110 |
Sodium hypochlorite used for purifying,disinfectants,fungicides in the field of water treatment;for disinfection and sterilization and algae eliminating in industrial water and swimming pool water;also used in organic matter decomposition,as well as for the removal of iron and manganese.
Harm and Countermeasure:sodium hypochlorite is better oxidant and causticity.People who using it must adorn shield to avoid be hurted.If be hurted,washing by sodium bicarbonate.
Packaging and storage:in the plastic barrel and avoiding ray.
Using:concentration is 30% and PH is under 6,added to water by measure pump of corrosion resistant.
