The method, inorganic compounds, say again smelly alkali, smelly soda, yellow alkali, LiuHuaJian. Pure show colorless crystalline powder. Hygroscopic strong sex, soluble in water. A strong alkali solution reaction. Touching skin and hair will cause burns. So the method known as LiuHuaJian. 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, and ChaoXie carbonated newly metamorphism, 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.
