What is a Sodium chlorite (NaClO₂)?

Sodium chlorite (NaClO₂) is the sodium salt of chlorous acid (HClO₂). It is a colorless or pale yellow powder or crystal, highly soluble in water. Sodium chlorite is primarily used as a strong oxidizing agent, playing a key role in applications like bleaching, disinfection, and water treatment. It is an effective bleaching agent, particularly in the paper and textile industries. In water treatment, sodium chlorite is used to disinfect water, and in the food industry, it serves as a disinfectant under regulated conditions. It also has antimicrobial properties, making it useful in disinfection processes to eliminate bacteria and viruses.

Sodium chlorite can be hazardous, as it is a strong oxidizer and may release chlorine gas under certain conditions. Proper safety measures, such as gloves, goggles, and adequate ventilation, are essential when handling it.
