Iron (III) Ammonium Sulfate – ProChem, Inc.

Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH4)2Fe(SO4)2(H2O)6. Containing two different cations, Fe 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. Like the other ferrous sulfate salts, ferrous ammonium … WebDilute 0.863 g of FeNH4(SO4)2,12H2O in 25 mL of dilute sulfuric acid 2.
