These properties include:
Chemical Composition
Sodium chlorite is a chemical compound with the formula NaCl2. Usually, it consists of sodium, chlorine, and oxygen elements. Besides, it comes in the form of a white or yellowish powder or crystalline solid. This powder is often produced in the laboratory or the chemical industry. Additionally, it has a chlorine-like odor, though faint and not as strong.
Solubility
Habitually, sodium chlorite is highly soluble in water. Normally, its solubility increases with temperature. This makes it suitable for bleaching and disinfecting since it dissolves easily for application. Moreover, it has low solubility in organic solvents like alcohol and acetone.
Stability and Storage
Normally, sodium chlorite is stable when stored in a cool and dry environment. Though stable, it needs to be kept away from heat, acids, and organic materials. These elements can trigger its decomposition. Additionally, proper containers should be airtight to prevent moisture from diluting it.
Reactivity
Customarily, this chemical is non-flammable. However, when exposed to acidic substances or organic materials, it generates chlorine dioxide. Chlorine dioxide is a extremely hazardous compound. Ideally, it can pose serious risks to health and the environment. Moreover, sodium whitener should be handled with due care to avert potential reactions.
pH Level
This chemical has a slightly alkaline nature. Normally, it has a pH level of 6-8 when dissolved in water. This makes it neutral for applications in water treatment and bleaching without adding acidity.
Occupational Safety and Health Administration (OSHA) Regulation
Usually, in cases where sodium chlorite is applied habitually, employers are mandated by OSHA to provide effective safety equipment. Some examples of such equipment include personal protective gear and first aid supplies. These supplies should be easily accessible. Moreover, it is imperative for employers to comprehend the hazards linked to sodium chlorite exposure. Also, take preventive measures to protect their workers.
Sodium chlorite is used in variegated fields when applying it.
Some of its common applications include:
Sodium Chlorite in Water Treatment
