Sodium Sulfate Anhydrous
Product:
NuGenTec Inorganic Chemical Group (NICG) Sodium Sulfate Anhydrous, is the sodium salt of sulfuric acid. Anhydrous, it is a white crystalline solid of formula Na2SO4. Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping. In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions. Lately, sodium sulfate has been found effective in dissolving very finely electroplated micrometer gold that is found in gold electroplated hardware on electronic products such as pins, and other connectors and switches. It is safer and cheaper than other reagents used for gold recovery, with little concern for adverse reactions or health effects. |
