-4 Aim To prepare double salts: ferrous ammonium sulphate (Mohr’s salt) and potash alum. Theory When a mixture containing equimolar proportions of potassium sulphate and aluminium sulphate or ferrous sulphate and ammonium sulphate is crystallised from its solution, a double salt is formed. The formation of double salt may be shown as follows: K2SO4 + Al2 Mohr's salt is a pale green crystalline solid which is soluble in water. It is a 'double sulfate' which contains two cations, one of which is Fe2+.

The formation of double salt may be shown as follows: K2SO4 + Al2 Mohr's salt is a pale green crystalline solid which is soluble in water. It is a 'double sulfate' which contains two cations, one of which is Fe2+. The identity of the second cation was determined by heating solid mohr's salt with solid sodium hydroxide and a colourless gas was evolved. The gas readily dissolved in watdr giving an alkaline About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators 2009-11-27 · Mohr's salt provides a stable alternative which can be weighed out to provide a stable solution containing a known concentration of ferrous ions uncontaminated by ferric salts. 2) Mohr's salt is a double salt, ferrous ammonium sulphate (hexahydrate), FeSO4.(NH4)2SO4.6H2O, so it contains Fe++, NH4+ and SO4= ions. Densities of double salt (NH4 Fe (So4)2.6H2o) dissolved in distilled water and in ethylene glycol at three temperatures (298.15,303.15 and 308.15)k have been utilized to calculate the apparent Mohr salt,a double salt of ammonium sulphate and ferrous sulphate it is a primary source of a soluble iron (II) (ferrous) salt.

2010-01-20 · Ammonium iron(II) sulfate, or Mohr's Salt, is a double salt of iron sulfate and ammonium sulfate, with the formula [NH4]2[Fe][SO4]2·6H2O. 2017-09-15 · Mohr’s salt i.e.

What is Mohr’s salt or Ferrous Ammonium Sulphate? 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. Ferrous Ammonium Sulfate also inferred as ammonium Iron (II) sulphate, or Mohr’s salt is having a chemical formula of (NH4)2Fe (SO4)2.

Mohr's salt is named after the German chemist Karl Friedrich Mohr, who made many important advances in the methodology of titration in the 19th century [1]. Due to the existence of active ions in Mohr's salt, therefore, we decided to study its catalytic activity in a three-component reaction. $\begingroup$ To put an answer, and prevent link rot, quoting Wikipedia with my emphasis, "Mohr's salt is the preferred source of ferrous ions as the solid has a long shelf life, being resistant to oxidation.

FeSO 4. 6H 2 O. The chemical name for Mohr’s salt is ferrous ammonium sulfate. In this titration Mohr salt acts as a reducing agent and potassium permanganate acts as an oxidising agent. Mohr’s salt or ammonium ferrous sulphate is the inorganic compound with the formula (NH4)2 Fe (SO4)2.6H2O containing two different cations Fe2+ and NH4+. It is classified as a double salt of ferrous sulphate and ammonium sulphate. It is a common laboratory reagent.
