Key Properties
Sodium chlorite is a strong oxidizing agent and a versatile chemical compound primarily used as a precursor for chlorine dioxide, which is a widely utilized disinfectant and bleaching agent. It is classified as an inorganic salt and is notable for its high reactivity and ability to release chlorine dioxide when acidified. Sodium chlorite is commonly employed in various industrial applications, including water treatment, pulp and paper bleaching, and textile processing. Its strong oxidizing properties make it effective in eliminating bacteria, viruses, and other pathogens, thereby ensuring safe drinking water and hygienic conditions in various settings.
Also known as Sodium chlorite, Chlorite of soda.

- Substance
Sodium chlorite appears as a white to pale yellow crystalline powder. It has a melting point of approximately 270 °C (518 °F) and is highly soluble in water, with a solubility of about 7.5 g/100 mL at 20 °C. The compound has a density of 2.5 g/cm³ and exhibits a strong oxidizing odor. It is hygroscopic, meaning it can absorb moisture from the air, which can affect its stability and reactivity. The compound is stable under normal conditions but should be stored away from heat and combustible materials to prevent any hazardous reactions.
