Ferrous ammonium sulfate | FeH8N2O8S2 - PubChem

Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 Fe(SO 4) 2 (H 2 O) 6.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.

The standard used in this experiment is ferrous ammonium sulfate, FeSO 4 (NH 4) 2 SO 4 6H 2 O. Because of the waters of crystallization, the compound is not a primary standard (it cannot be dried). However, the purity (>99%) is sufficient for spectrophotometric analysis, which produces results with relative accuracies in the 1 to 2% range.

In this experiment you will mix solutions of iron(II) sulfate and ammonium sulfate to obtain pale blue-green crystals of Mohr's salt. Mohrs salt is an example of a 'double salt', i.e. it contains the same ions as in FeSO4.7H2O and (NH4)2(SO4). It is simple to prepare because it is less soluble than either of its constituent salts. A
