Formula: Na2S2O5 Molecular Weight: 190.09 Appearance: white or slightly yellow crystalline powder or small crystals of sulfur dioxide smell, sour, salty,; Storage falling yellow color gradient Specification: ≥ 65% iron sulfur ≤ 0.005% Water insoluble ≤ 0.05 % PH value 4.0-4.6 Chinese chemical name: sodium metabisulfite Chemical Name: sodium metabisulfite Chinese name 2: sodium metabisulfite Name 2: sodium pyrosulfite / sodium metabisulphite Technical Manual Code:. 1333 CAS No :7681-57-4 MF: NaS2O5 MW: 190.09 Packing and storage: 1. Bags (barrel) should be painted on the firm's logo, including: name, grade, weight and production plant name; 2. Sodium metabisulfite with plastic bags or drums Shouguang sodium metabisulfite, lined with plastic bag, net weight 25 or 50kg; 3. This product transportation, storage should prevent damage, moisture, heat deterioration. Prohibited with oxidants, acids coexist; 4. The product from the date of manufacture, storage period of six months. Properties: Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong smell of SO2, the proportion of 1.4 metabisulfite price, sodium metabisulfite dissolved in water, acidic aqueous solution, then emit SO2 in contact with strong acids to form the corresponding salts sodium metabisulfite phone manufacturers, long home air, the oxidation of Na2S2O6, so the product can not go far. Higher than 1500C, ie the decomposition of SO2. Sodium metabisulfite | metabisulfite Price | Rui Desheng Chemical provided by 瑞德胜 chemical.
