Sodium chlorite, with the formula NaClO2, is the sodium salt of chlorous acid. Recognized by its CAS number 7758-19-2, it serves primarily as an oxidizing or bleaching agent, notable for its potent oxidizing power and distinctive pungent odor.
Its main applications include bleaching textiles like pulp, cotton, and hemp; decolorizing paper, fats, oils, and sucrose; surface treatment of printed circuit boards; denitration; and wastewater treatment. Sodium chlorite is a food additive, used as a bleaching agent and disinfectant, albeit with the condition of its removal before food consumption. It is also utilized in water treatment disinfection and as a cleaning agent for contact lenses.
Sodium chlorite appears as colorless, hygroscopic crystals at room temperature, with a molecular weight of 90.44 and decomposes between 180-200°C. It has a density of 2.5 g/mL and dissolves well in water (39 g/100 ml).
Available as both a research reagent and an industrial chemical, sodium chlorite is marketed in various forms and concentrations.
For laboratory use, it comes in quantities like 5g, 100g, 500g, 2kg, and 10kg, often with sodium carbonate as an impurity. Primarily used in synthetic organic chemistry as an oxidizing agent, these reagents are stored at room temperature.
Industrially, sodium chlorite is available both as a pure substance and in solution (e.g., 25% solution), predominantly used for its bleaching and oxidizing properties. Purchasers typically consult manufacturers for specific volumes.
It is produced by reacting chlorine dioxide with sodium hydroxide and hydrogen peroxide.
Sodium chlorite generates chlorine dioxide when treated with chlorine or sodium hypochlorite in aqueous solution, also producible by electro-oxidation or UV light exposure. It decomposes thermally into sodium chlorate and chloride, and is used in synthetic organic chemistry, particularly in oxidation reactions.
As a strong oxidant, sodium chlorite poses risks of toxicity, skin and eye damage, organ harm (specifically to the spleen) upon prolonged exposure, and is highly toxic to aquatic life. It is regulated under multiple laws, classified as a hazardous substance, necessitating strict handling and labeling as per legal requirements.
