Introduction to Sodium Chlorite (CAS No. 7758-19-2)

What Is Sodium Chlorite?

Sodium chlorite is a powerful chemical compound with the formula NaClO₂. It’s widely used in disinfection, water treatment, and even some medical applications. But what makes it so special? Let’s break it down.

Chemical Identification

With the CAS No. 7758-19-2, sodium chlorite is easily identifiable in chemical databases. This number ensures you’re dealing with the right substance, whether for industrial or research purposes.

Physical Appearance

Ever seen a white crystalline powder? That’s sodium chlorite in its most common form. It dissolves easily in water, making it super practical for liquid applications.

Chemical Properties of Sodium Chlorite

Molecular Structure

Sodium chlorite consists of sodium (Na⁺) and chlorite (ClO₂⁻) ions. This structure gives it strong oxidizing properties—meaning it can break down contaminants effectively.

Solubility and Stability

It loves water! Sodium chlorite dissolves quickly, but it’s also sensitive to heat and light. Store it in a cool, dark place to keep it stable.

Reactivity with Other Compounds

Mix it with acids? Bad idea. It releases chlorine dioxide, a gas that can be hazardous in high concentrations. Always handle it carefully!

How Is Sodium Chlorite Produced?

Industrial Manufacturing Process

Most sodium chlorite is made by reducing chlorine dioxide into a sodium hydroxide solution. The result? A highly useful disinfectant ready for multiple industries.

Key Raw Materials

Chlorine dioxide and sodium hydroxide are the main players here. Without them, we wouldn’t have sodium chlorite as we know it.
