What is ammonium iron (II) sulfate?
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2Fe(SO 4) 2·6H 2O. 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 by air.
Why is ferrous ammonium sulfate used as a reagent?
It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation by air. Like the other ferrous sulfate salts, ferrous ammonium sulfate dissolves in water to give the aquo complex [Fe (H 2 O) 6] 2+, which has octahedral molecular geometry.

What kind of test method is ferrous ammonium sulfate?
A buffered DPD indicator powder is added to a water sample and reacts with chlorine to produce the pink color characteristic of the standard DPD test. Ferrous ammonium sulfate (FAS) is then added drop by drop until the pink color completely and permanently disappears, signaling the endpoint of the reaction.
Is Ferrous ammonium sulphate is double salt?
Mohr's salt is also called as double salt which contain more than one simple salt. It undergoes complete dissociation in aqueous solutions. Mohr's salt dissociates into Fe2+, NH4+, SO42- ions and give their individual chemical test. Mohr's salt is light green transparent octahedral crystals.
Is Ferrous ammonium sulphate a primary standard?
Known as Mohr's salt, ferrous ammonium sulfate is used as a primary standard in quantitative analysis. It is also used in photographic solutions and in Dosimeter badges.
In which method ferric ammonium sulphate is used as indicator?
Chemical analysis is the name of the method when ferric ammonium sulphate is used as the indicator. Basically, this method is used in the making of pharma elements. It is used in standardizing the formulation.
What is the chemical formula of ferrous ammonium sulphate?
(NH₄)₂Fe(SO₄)₂·6H₂OAmmonium iron(II) sulfate / Formula
Why Ferrous ammonium sulphate is called Mohr salt?
It derives its name from the German chemist Karl Friedrich Mohr, a 19th century pioneer in the development of titration methodology. 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.
What type of salt is Mohr's salt?
Therefore, Mohr's salt can be categorized as a double salt of ammonium sulfate and ferrous sulfate. It is important to note that Mohr's salt is a common laboratory reagent since it readily undergoes crystallization and the crystals formed by it are quite resistant to oxidation in the presence of air.
Is ammonium sulfate an acid or base?
acidicIs ammonium sulfate an acid or base? The reaction between the sulphuric acid and the ammonium hydroxide produces ammonium sulfate. Sulphuric acid is a strong acid and ammonium hydroxide is a weak base. Therefore, the salt formed by ammonium sulphate is acidic.

Why Mohr salt is used as a source of Fe2+ rather than feso4?
Thus, the correct option is (C) Mohr's salt contains only ferrous ions whereas ferrous sulphate contains some ferric ions.
What is the reaction between iron (II) sulfate and ammonium nitrate or
Reaction between iron (II) sulfate and ammonium nitrate or chloride. is required. Add to the flask with saturated iron (II) sulfate solution a ammonium salt solution with stirring. Freezing this mixture will cause forming a large amount of crystalline precipitationof Mohr's salt.
What is the effect of iron sulfate on crystals?
Excess of ammonium sulfate influenses on crystal shape and leads to transparency deterioration. Addition of glycerol leads to flattening of crystal shape and positively influences on transparency.
What solution to use to make Mohr's salt?
is required. Add to the flask with saturated iron (II) sulfate solution a ammonium salt solution with stirring. Freezing this mixture will cause forming a large amount of crystalline precipitationof Mohr's salt.
How to purify unreacted compounds?
For purifying compound from unreacted compounds add large amount of cold ethanol or acetone to solution, salt will settle to the bottom in the form of fine crystals or powder. Filter precipitate and wash it with small amount of the same solvent, then filter the solution and use it for crystal growing.
