What is the role of ammonia in limit test of iron?
In the limit test for iron, ammonia is used to adjust the pH of the solution to alkaline conditions. This helps to precipitate iron as iron hydroxide, making it easier to separate and quantify. Ammonia also helps to prevent the interference of other substances in the test.
Why ammonia solution used in iron limit test?
Ammonia solution is used in the iron limit test to precipitate iron as iron(III) hydroxide. This allows for easy separation and identification of iron in the solution. The formation of a yellow-orange precipitate indicates the presence of iron.
Why ammonia is used in iron limit test?
purple colour of ferrous thioglycolate is formed only when alkaline medium is maintained, it can be done by using dil.ammonia in presence of citric acid.
When iron II sulphate reacts with ammonia would it form iron hydroxide or ferrous ammonia sulphate or ammonia iron II sulphate?
When iron II sulphate reacts with ammonia, it forms ferrous ammonia sulphate [Fe(NH3)2(SO4)2]. This compound is a coordination complex in which the iron atom is surrounded by ammonia molecules and sulfate ions.
Will ammonia melts iron?
No, ammonia will not melt iron. Ammonia is a compound made of nitrogen and hydrogen, and it does not have the ability to melt metals like iron, which requires much higher temperatures to change its state.

Why ferrous and ferric not form compounds with ammonia?
What is observed is is that ammonia acts as a base and precipitates iron(III) solutions as iron(III) hydroxide. Similar problems are encounteerd with iron(II). The underlying reason is that iron(III) does not bond strongly to N donors. iron(II) also does not bond strongly. It is possible to make the [Fe(NH3)6] 3+ ion and I suspect that this is made in liquid ammonia, avoiding the probelm of interaction with water. Certainly other iron(II) salts dissolve in liquid ammonia to give ammine complexes although some are quite unstable.
Why Citric acid use in limit test for iron?
It forms a complex with iron which prevents the precipitation of ferrous or ferric hydroxide after the addition of ammonia to make the solution alkaline

Why is citric acid used in limit test for iron?
Citric acid is used in the limit test for iron because it forms a soluble complex with iron ions, which helps to prevent precipitation of iron during the test. This allows for a more accurate determination of the iron content in the sample.
Does iron covert elments carbon hydrogen and oxygen to ammonia?
No, Iron converts Nitrogen gas, methane gas and water into ammonia gas and carbon dioxide.
What happens when Ammonia and iron 3 mix?
When ammonia and iron(III) mix, they can form a complex known as tetraammineiron(III) ion ( [Fe(NH3)4(H2O)2]3+ ). This complex is a coordination compound consisting of iron ion surrounded by ammonia ligands. This reaction is an example of coordination chemistry where ammonia acts as a ligand to the iron ion.
What is the catalyst for ammonia?
The catalyst for the production of ammonia through the Haber-Bosch process is typically iron with a promoter like potassium oxide or alumina. This catalyst helps lower the activation energy required for the reaction to convert nitrogen and hydrogen into ammonia.
What is the catalyst used to make sulfuric acid nitric acid ammonia ethene and magarine?
Ammonia = iron catalyst
