  2. NFPA 704 - Wikipedia

    en.wikipedia.org/wiki/NFPA_704

    "NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [ 1 ] and revised several times since then, it defines the " Safety Square " or " Fire Diamond " which is used to ...

  3. Iron (II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_sulfate

    Iron(II) sulfate outside a titanium dioxide factory in Kaanaa, Pori, Finland. Upon dissolving in water, ferrous sulfates form the metal aquo complex [Fe(H 2 O) 6] 2+, which is an almost colorless, paramagnetic ion. On heating, iron(II) sulfate first loses its water of crystallization and the original green crystals are converted into a white ...

  4. Sodium persulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_persulfate

    The sulfate radical formed in situ has a standard electrode potential of 2.7 V. However, there are a few drawbacks in utilizing platinum anodes to produce the salts; the manufacturing process is inefficient due to oxygen evolution and the product could contain contaminants coming from platinum corrosion (mainly due to extremely oxidizing nature ...

  6. Ammonium iron(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_iron(II)_sulfate

    Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O. Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate. It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation ...

  7. Fenton's reagent - Wikipedia

    en.wikipedia.org/wiki/Fenton's_reagent

    Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene).
