    Ammonium iron(II) sulfate Wikipedia

    Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 Fe(SO 4) 2 ·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 by air.
