E Mohr salt 392/1
Mohr Salt is Ammonium Iron (II) Sulphate, named after the German chemist Karl Friedrich Mohr.
Mohr salt is (NH4)2Fe(SO4)2·6H2O. This name was attributed in the honor of the German chemist Karl Fiedrich Mohr.
n factor for mohr salt is 1.
The Mohr salt is more stable to oxidation of Fe2+ to Fe3+.
The Mohr salt is ammonoim iron sulfate - (NH4)2Fe(SO4)2.6H2O.
For preparation of standard solution of Mohr salt {FeSO4.(NH4)2SO4.6H2O}, it's necessary to add dilute H2SO4 to prevent the Fe2+ ions of Mohr salt solution from undergoing oxidation (to Fe3+).
The molar and equivalent mass of Mohr salt is 392,14; the chemical formula is: (NH4)2Fe(SO4)2.6H2O.
due to the presence of ferrous ions.
