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.
For example, addition of barium chloride, precipitates out barium sulfate. The filtrate on evaporation yields ammonium chloride . Ammonium sulfate forms many double salts (ammonium metal sulfates) when its solution is mixed with equimolar solutions of metal sulfates and the solution is slowly evaporated.
Ammonium cerium(IV) sulfate is an inorganic compound with the formula (NH 4) 4 Ce(SO 4) 4 ·2H 2 O. It is an orange-colored solid. It is an orange-colored solid. It is a strong oxidant, the potential for reduction is about +1.44V.
Ammonium sulfite can be prepared by the reaction of ammonia with sulfur dioxide in aqueous solution: . 2 NH 3 + SO 2 + H 2 O → (NH 4) 2 SO 3. Ammonium sulfite is produced in gas scrubbers, now obsolete, consisting of ammonium hydroxide to remove sulfur dioxide from emissions from power plants.
An example of a reaction forming an ammonium ion is that between dimethylamine, (CH 3) 2 NH, and an acid to give the dimethylammonium cation, [(CH 3) 2 NH 2] +: Quaternary ammonium cations have four organic groups attached to the nitrogen atom, they lack a hydrogen atom bonded to the nitrogen atom.
Ammonium sulfate is an inorganic salt with a high solubility that disassociates into ammonium (NH + 4) and sulfate (SO 2− 4) in aqueous solutions. [1] Ammonium sulfate is especially useful as a precipitant because it is highly soluble, stabilizes protein structure, has a relatively low density, is readily available, and is relatively inexpensive.
