Detailed Description
Sodium sulfide Molecular formula: Na2S. 9H2O CAS: 1313-84-4 Appearance: Colorless crystal powder Sodium sulfide Properties: The method solution in the air will slowly oxidized to glucosinolate and sodium, sodium sulfite, or sodium and more show. Because of glucosinolate and sodium generating speed faster, so the oxidation of major product is glucosinolate and sodium. The method in the air, constantly release hydrogen sulfide gas. Industrial method for containing impurities its colour and lustre are pink and palm red and yellow. Specific gravity, melting point, boiling point, but also because of impurities influence and different. Use: Analytics reagents used as cadmium, such as metal ions of precipitation agent. Also used in photographing, mineral flotation, metal processing, zinc and cadmium electroplating. Magnesium Chloride Food Additives Chemicals»Inorganic Salt»Chloride Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. 1, Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2(H2O)x. These salts are typical ionic halides, being highly soluble in water. 2, Magnesium chloride is an important coagulant (E511 [8][clarification needed]) used in the preparation of tofu from soy milk. In Japan it is sold as nigari (, derived from the Japanese word for "bitter"), a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated. In China it is called lushui, Nigari or lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk.
