Ammonium Ferrous Sulphate:

Ammonium Ferrous Sulphate, also known as Mohr’s salt, is an inorganic compound with the chemical formula (NH₄)₂Fe(SO₄)₂·6H₂O. Let’s break it down:

• Appearance: It appears as a blue-green solid.
• Structure: Mohr’s salt belongs to a group of double sulfates called Schönites or Tutton’s salts. Its crystals consist of octahedral [Fe(H₂O)₆]²⁺ centers, which are hydrogen-bonded to sulfate and ammonium ions.
• Uses:
  • Laboratory Reagent: Mohr’s salt is commonly used in laboratories because it is readily crystallized and resistant to oxidation by air.
  • Source of Ferrous Ions: It serves as a preferred source of ferrous ions for various chemical processes.
  • Titration: It is preferred over iron(II) sulfate for titration purposes due to its resistance to oxidation by oxygen in the air.
