Synonym: Ammonium ferrous sulfate hexahydrate, Ammonium iron(II) sulfate, Mohr’s salt Linear Formula: (NH 4 ) 2 Fe(SO 4 ) 2 · 6H 2 O Molecular Weight: 392.14 Mohr salt is a double salt forming a single crystalline structure having the formula (NH 4

Mohr salt

Mohr’s salt is a light green colour crystalline inorganic compound. It is a double salt of FeSO4.7H2O and (NH4)2SO4 which belongs to a group of double sulfate named Schonites or tutton’s salts, { formula: M2M’ (SO4)2.6H2O where M is univalent and M’ is divalent ions. Mohr’s salt is used in analytical chemistry as the preferred source of ferrous ions due to the solid’s extended shelf life and resistance to oxidation. Sulfuric acid is often added to solutions using ferrous ammonium sulfate in order to reduce the oxidation of the ferric iron.

Part of the reason I was so excited was because Mohr’s salt is supposedly much more stable compared to pure iron (II) sulfate. This means it does not oxidize and turn brown easily. Ammonium iron (II) sulfate, more commonly referred to as Mohr's salt, is an inorganic chemical compound with the formula (NH4)2Fe (SO4)2·6 H2O as hexahydrate. Containing two different cations, Fe 2+ and NH 4+, it is classified as a double salt of ferrous sulfate and ammonium sulfate.

The solutions used for the determination of COD are: Sulfuric acid (H2SO4), silver sulfate (Ag2SO4), Mohr's salts (iron solution and ammonium (NH4) 2Fe (SO4) 26H2O), bichromate of potassium (K2Cr2O7) and ferroin (FeSO4, 7H2O) as an indicator dye.

Is it done to prevent oxidation of F e X 2 + to F e X 3 + before the titration itself?
