Sodium Hydrosulfite

Sodium Hydrosulfite (chemical formula Na2S2O4) is a white to pale yellow crystalline powder widely employed as a reducing agent in various industrial processes. It is highly soluble in water and typically supplied in granular or powder forms with purities suitable for applications requiring oxidative neutralization and reduction reactions. Handling precautions include avoiding contact with moisture and strong oxidizers to maintain stability during storage. For industrial buyers, Sodium Hydrosulfite's reliable concentration, often around 85-90% active ingredient, enables consistent dosing in manufacturing processes such as water treatment and textile processing. Dosage rates commonly vary from 50 up to 300 ppm depending on application specifics. Temperatures above 40°C during storage or handling should be avoided as elevated heat can accelerate decomposition. Buyers should confirm product specifications and storage conditions with the Safety Data Sheet (SDS) provided on delivery.

In water treatment, residual chlorine and chloramines can cause corrosion in piping and harm aquatic life when present beyond acceptable levels. Sodium Hydrosulfite effectively removes these residual oxidants through reduction, protecting infrastructure and ecosystems. Without this neutralization step, facilities risk accelerated equipment degradation and regulatory non-compliance. Additionally, in textile manufacturing, incomplete removal of natural fibers' color Impurities reduces dye uptake and uniformity. Using Sodium Hydrosulfite for bleaching ensures fabric brightness and consistent coloration, improving product quality and reducing waste. Effective reduction agents like Sodium Hydrosulfite are essential to maintain process efficiency and end-product standards.
