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 ...
Mohr's salt, ammonium iron(II) sulfate, [NH 4] 2 [Fe(H 2 O) 6](SO 4) 2.. A double salt is a salt that contains two or more different cations or anions.Examples of double salts include alums (with the general formula M I M III (SO 4) 2 ·12H 2 O) and Tutton's salts (with the general formula (M I) 2 M II (SO 4) 2 ·6H 2 O).

Ammonium iron(III) sulfate, NH 4 Fe(SO 4) 2 ·12 H 2 O, or NH 4 [Fe(H 2 O) 6](SO 4) 2 ·6 H 2 O, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB(SO 4) 2 · 12 H 2 O. [2] It has the appearance of weakly violet, octahedrical crystals.
Karl Friedrich Mohr (November 4, 1806 – September 28, 1879) was a German chemist famous for his early statement of the principle of the conservation of energy. Ammonium iron(II) sulfate, (NH 4 ) 2 Fe(SO 4 ) 2 .6H 2 O, is named Mohr's salt after him.

Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known.
The first extraction of pure phosphorus came from this salt in the 17th century, when Hennig Brandt attempted to extract gold from urine. Microcosmic salt is used in the laboratory as an essential ingredient of the microcosmic salt bead test for identification of metallic radicals on the basis of the color they produce in oxidising or reducing ...
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds.It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods.
