What is Mohr’s Salt?
Mohr’s salt, also known as Ferrous Ammonium Sulfate, is a chemical compound with the formula (NH4)2Fe(SO4)2·6H2O. It is a double salt of iron(II) sulfate and ammonium sulfate. The chemical structure shows that it contains two ammonium ions (NH4⁺), one iron(II) ion (Fe²⁺), two sulfate ions (SO4²⁻), and six water molecules (H2O) in its hydrated form.
Note: Mohr’s salt is commonly utilized as a laboratory reagent due to its easy crystallization and the production of crystals that exhibit high resistance to oxidation when exposed to air.
Mohr’s Salt
Mohr’s Salt is named after the German chemist Karl Friedrich Mohr, who synthesized it in 1855. In analytical chemistry, Mohr’s salt is frequently used as a primary standard to standardize solutions of other substances, especially when titrating permanganate solutions. In addition, it finds use as a fertilizer in agriculture and various laboratory applications. In this article, we will discuss the various concepts related to Mohr’s Salt.
