CAS number : 7727-21-1
Molecular weight :270.32
Molecular formula/chemical symbol : K2S2O8
Description :
Colorless or white
crystals dissolve in water, the solution is acidic, insoluble in alcohol. With
moisture or heat gradually decompose to release oxygen. Odorless. Gradual
decomposition of the loss of available oxygen, moisture can promote the
decomposition, and rapid decomposition at high temperatures, decompose at about
100 ℃.
Dissolved in 25 parts of water dissolved in about 50 parts of water (40 ℃),
insoluble in ethanol, acidic aqueous solution. There are strong oxidizing. With
organic friction or impact can cause a fire. There are strong irritant.
USES :
Analytical reagent, oxidant, develop photos.
Polymerization initiator. The photographic processing (vulcanization sulfate
was removed).
