关键的区别——亚氯酸钠vs Hypochl钠orite
Sodium chlorite and sodium hypochlorite are common sodium salts used in industries. Both these compounds are very important as bleaching agents and disinfectants. But they are very different from each other when their chemical properties such as molar mass and physical properties are considered. Sodium chlorite is mainly used in paper manufacturing and as a disinfectant. Sodium hypochlorite is used as a disinfectant by dissolving it in water to form “liquid bleach”. The key difference between sodium chlorite and sodium hypochlorite is thatsodium chlorite contains chlorine atoms having +3氧化状态而次氯酸钠含有+1氧化态的氯原子。

What is Sodium Chlorite?
亚氯酸钠是具有化学配方naclo的无机化合物2。The摩尔质量of this compound is 90.438 g/mol when it is无水。There is a hydrate form as well (composed of three water molecules associated with the sodium chlorite molecule whose molar mass is 144.48 g/mol). The compound is also called chlorous acid. It is anionic compound其中包含一个sodium阳离子(Na+)和绿色阴离子(clo2-)。
It is available as a white crystalline powder which is odorless. The burning of sodium chlorite is difficult, but it can accelerate the burning of organic compounds. Therefore, sodium chlorite can be used to make explosive mixtures with易燃材料。亚氯酸钠在约180-200℃下分解。
亚氯酸钠不易溶于水,但更易溶甲醇和乙醇。The crystal structure of the compound is monoclinic. Sodium chlorite is mainly used in the manufacturing of paper and also as a disinfectant. It is a good氧化剂;因此,用于漂白各种类型的材料,例如木材,油等。
The free chlorous acid (HClO2) is very unstable and it has no considerable importance in industries. But the sodium salt of this acid is very stable and also inexpensive. Most of the times, sodium chlorite is derived from sodium chlorate, which has the chemical formula NaClO3。生产过程是一种间接方法,其中二氧化氯(CLO)2) is produced at first. Chlorine dioxide is very explosive and it is made by reducing sodium chlorate in a strong acid in the presence of a reducing agent like sodium sulfite. The produced chlorine dioxide is then absorbed to an碱解决方案以及减少过氧化氢(H2o2)。这产生了氯酸钠。
什么是次氯酸钠?
次氯酸钠是具有化学式NaClo的无机化合物。钠,氯和氧之间的原子比为1:1:1。该化合物由与次氯酸盐阴离子结合的钠阳离子组成。因此,它是次伐多酸的钠盐。当次氯酸钠溶解在水中时,由于其漂白特性,它被称为液相漂白剂。
The molar mass of sodium hypochlorite is 74.44 g/mol. The appearance of this compound can be described as a greenish yellow solid. It also has a sweet odor. The melting point of sodium hypochlorite is 18°C and the boiling point is 101◦C.
Sodium hypochlorite is mainly used as a disinfectant and as a bleaching agent. Almost all the bleaching liquid we use in household contain around 3-8% of sodium hypochlorite. This compound has de-staining properties; hence it is used to remove mold stains, dental stains, etc. Sodium hypochlorite is a good disinfectant since it has a broad range of anti-microbial activity.
次氯酸钠的产生是通过妓女工艺完成的。这是一种大规模的工业方法。在这里,次氯酸钠是通过将氯气转入冷的稀氢氧化钠溶液中产生的。该方法给出的其他产品是氯化钠(NACL)。
亚氯酸钠和次氯酸钠之间有什么相似之处?
- 亚氯酸钠和次氯酸钠由Na,Cl和O原子组成。
- 两者都是好的消毒剂。
