More information:

Property: Colorless transparent crystal or white crystal. Specific gravity 1.79, PH value 6.8-8, melting point 70-80ºC, slightly weathering in hot air. At 60ºC, part of the water of crystallization begins to be lost, at 100ºC, 3 water molecules are lost, and at 215ºC, it becomes anhydrous salt, easily soluble in water, and the solution is slightly alkaline.

Specifications: Conform to FCC (IV) and enterprise standards

Uses: It is used as reducing agent in plate making in printing industry, mirror making and thermos bottle industry; complexing agent in electroplating industry; crystal speaker and microphone in telecommunications industry; ADA desulfurizer in fertilizer industry; it is used in glass or other industries; For the monitoring of reducing sugar in food, it is added to Fehling's reagent to generate copper tartrate to promote the generation of cuprous oxide; it is used to shield metal ions in chemical analysis.

Packing: 25kg composite paper bag lined with polyethylene bag.
