Description

This container holds Ammonium Ferrous Sulphate, a high-quality laboratory reagent provided in a 500g quantity. Also commonly known as Mohr’s salt, it is a double salt of ferrous sulfate and ammonium sulfate with the chemical formula (NH4​)2​SO4​⋅FeSO4​⋅6H2​O and a molecular weight of $392.13\text{ g/mol}$. In its pure state, it typically appears as pale green, monoclinic crystals. It is highly valued in analytical chemistry as a preferred source of ferrous ions (Fe2+) because it is much more stable against oxidation by air than iron(II) sulfate alone, giving it a longer shelf life for titration purposes.
