Sodium Dithionite 88%, also known as Sodium Hydrosulfite, is a white crystalline powder with a weak sulfurous odor. It is a sodium salt of dithionous acid. Although it is stable under most conditions, it will decompose in hot water and in acid solutions. This compound is a water-soluble salt and can be used as a reducing agent in aqueous solutions.

This product is commonly used in industrial dyeing processes as a reducing agent. It helps reduce otherwise water-insoluble dyes into water-soluble alkali metal salts, improving overall color quality. Additionally, the reduction properties of Sodium Dithionite eliminate excess dye, residual oxide, and unintended pigments, making it an ideal product for dyeing processes.

Key Features:

• White crystalline powder with a weak sulfurous odor

Sodium Sulfite, Anhydrous, 98%

Sodium Sulfite, Anhydrous (Na₂SO₃), is a high-purity technical-grade compound with 98% Na₂SO₃ content, widely valued for its reducing and oxygen-scavenging properties. Commonly used in water treatment, it protects steam boilers and washing machines from corrosion by reacting with dissolved oxygen to form sodium sulfate. In the photographic industry, it prevents developer solutions from oxidizing and facilitates the removal of fixer from photo-paper and film. The textile industry utilizes Sodium Sulfite as a bleaching, desulfurizing, and dechlorinating agent, while the paper industry employs it in various processes. Additionally, it is used as a preservative to prevent discoloration in dried fruits and meats. Sodium Sulfite also functions as a reagent in sulfonation and sulfomethylation reactions. With a 98% purity level and low impurity content, this versatile compound is essential for numerous industrial and commercial applications.
