Basic Information

  • Chemical properties: Black purple, slender angular, granular, needle like or quicksand like crystals, with a blue metallic luster, odorless, sweet and astringent taste, sensitive to light. heated to about 240 ℃, decomposed with oxygen escaping, and decomposed when encountering ethanol and other organic solvents; It can also free oxygen from concentrated acid, and when it comes into contact with hydrochloric acid and free chlorine, it can be decomposed by most reducing substances, such as ferrous salts, iodides, and oxalates, especially when acid is present, it is more prone to oxidation. Easy to dissolve in boiling water, soluble in water. PH 7-9 (20g/L, H2O, 20 ℃). Melting point>240 ℃ (dec.). Density ρ (20) 2.70g/mL.
  • Usage: Oxidizer; disinfectant; Chemical synthesis; Clean water; Reagents for capacity analysis oxidation-reduction method determination; Reagents for chromatographic analysis; Used for emission spectroscopy analysis; Drip analysis of barium, silver, sulfate, iron, vanadium, and tin, clinical examination of exfoliated cells, etc.
