High Quality 88% 90% Sodium Dithionite for Textile
Product Description
Sodium dithionite, a strong reducing agent, has two forms: dihydrate salt and anhydrous salt. The dihydrate salt is light yellow flaky crystal, and its quality is extremely unstable. Exists only in alkaline solution. When heated to a certain temperature, it dehydrates and turns into anhydrous salt. The anhydrous salt is a white crystalline powder, which exists stably under normal temperature and drying.
