Which of the following is Mohr's Salt? |
Ammonium iron sulphate Ammonium iron chloride Ammonium iron nitrate Ammonium iron bromide. |
Ammonium iron sulphate |
The correct answer is option 1. Ammonium iron sulphate. Ammonium iron(II) sulfate, often known as Mohr's Salt, is an inorganic substance with the chemical formula FeSO4(NH4)2SO4.6H2O. Two main cations, ammonium (denoted by NH4+) and ferrous (denoted by Fe2+), are known to be present in this molecule. As a result, Mohr's salt might be regarded as a double salt composed of ferrous and ammonium sulfates. Mohr's salt, which quickly crystallizes and produces crystals that are remarkably resistant to oxidation in the presence of air, is an essential laboratory reagent. |
