Calcium chloride

Colorless cubic crystal, white or grayish white, granular, honeycomb block, spherical, irregular granular, powdered.Slightly toxic, odorless, slightly bitter taste.Hygroscopicity is very strong, easy to deliquescent when exposed to air.It is soluble in water and emits a large amount of heat (the enthalpy of dissolution of calcium chloride is -176.2 CAL /g). The aqueous solution is slightly acidic.Soluble in alcohol, acetone, acetic acid.When interacting with ammonia or ethanol, CaCl2·8NH3 and CaCl2·4C2H5OH complexes are generated, respectively.Under the low temperature solution crystallization and precipitation of six water content, heating gradually to 30 ℃ is dissolved in the crystallization of the water itself, continue to heat water loss gradually, to 200 ℃ when become dihydrate, heated to 260 ℃ was white vesicular anhydrous calcium chloride.

Sodium Pyrosulfite

Sodium metosulfite is white or yellow crystalline powder or small crystal, with strong smell of SO2, specific weight 1.4, soluble in water, the aqueous solution is acidic, contact with strong acid will release SO2 and generate the corresponding salt, long time in the air, it will be oxidized into Na2S2O6, so the product can not be stored for a long time.Above 150 degrees Celsius, SO2 is decomposed.
