Product Description
Sodium hydrosulfite, also known as sodium hydrosulfite, is a white sandy crystal or yellowish powder chemical. As sulfur is in the middle valence state, sodium dithionite has strong reducibility and strong oxidation.
Features:1. Slight special odor. Sensitive to light.
2. In the presence of moisture or aqueous solution, sodium bisulfite and sodium bisulfate are quickly generated and become acidic.
3. It is easily soluble in water, slightly soluble in ethanol, and the aqueous solution is neutral. Easy to burn when wet. Due to its unstable nature, a certain amount of stabilizer is added to the finished product.
